Do-it-yourself modification of spark plugs

Do-it-yourself modification of spark plugs. What and how should you do for a good result?

Such a question as modifying spark plugs with your own hands may be relevant for those who have a fairly old gasoline car.
The information is quite interesting. Let's see how such improvements are useful in practice? Firstly, even despite the severity of climatic and other conditions, the engine always starts very easily, without any nuances. Even when the mixture of fuel and air is not entirely optimal, the engine is stable at high speeds. When supercharged at high pressure, the possibility of blowing out the spark plug (when the spark is blown away) is reduced. The performance of the engine and its response to your actions improve, and gasoline burns quickly and much more completely. Hence, operating efficiency increases and fuel consumption decreases.

Modification of spark plugs to save fuel - Engine Master

Experienced motorists know that the engine in any car, like a person’s heart, gets so tired with age that sometimes it not only works poorly, but even stalls and then doesn’t want to start.

Therefore, he needs “treatment” more and more often. Moreover, replacing rings, pistons and valves does not always improve the efficiency of the internal combustion engine.

The ignition system and, first of all, the spark plugs also play a big role in this.

For a car with “experience”, the issue of starting the engine is very relevant, especially in areas with harsh climatic conditions. As you know, the size and shape of the spark discharge is of great importance.

The spark parameters are especially important when the engine is running cold, when the fuel mixture entering the combustion chamber is far from a gaseous state.

To improve the quality performance of the spark plug, a very simple modification is proposed, which can be done not only by a home craftsman, but also by any car enthusiast who knows how to hold a hammer and pliers.

Reducing the effect of blowing off the spark discharge will improve the ignition of gasoline and the completeness of combustion, which will immediately affect the engine response and the stability of its operation, especially at high speeds.

Do-it-yourself modification of spark plugs can be done according to the type of sports series products produced by some companies that develop spare parts. Such spark plugs significantly increase power and reduce consumption, and manufacturers provide guarantees of almost 100 thousand kilometers without any significant loss of quality functioning. But in practice everything looks much more modest.

The efficiency of these structures, despite their high cost, noticeably decreases after only 10 thousand km, and throwing them away and buying new ones is quite expensive. What can be done in such cases to preserve the candles longer and increase their intended effectiveness? Under no circumstances, do not throw it away! You need to try to modify them using simple procedures, which, according to the instructions, will not be so difficult even for an inexperienced driver. So, let's try to understand this process step by step.

Modifying spark plugs for a car is an easy way to improve the efficiency of an old engine.

Experienced motorists know that the engine in any car, like a person’s heart, gets so tired with age that sometimes it not only works poorly, but even stalls and then doesn’t want to start.

Therefore, he needs “treatment” more and more often. Moreover, replacing rings, pistons and valves does not always improve the efficiency of the internal combustion engine.

The ignition system and, first of all, the spark plugs also play a big role in this.

The spark parameters are especially important when the engine is running cold, when the fuel mixture entering the combustion chamber is far from a gaseous state.

It should also be noted that the proposed modification will be useful not only for carburetor internal combustion engines. It will help improve the performance of injection systems and even turbocharged engines. Reducing the effect of blowing off the spark discharge will improve the ignition of gasoline and the completeness of combustion, which will immediately affect the engine response and the stability of its operation, especially at high speeds.

Stage-by-stage development

In order for the spark plug to become effective again, we need to use a simple tool to make the electrode on the side shorter, and then start adjusting the gap. Moreover, the shortening must be done so that the central electrode does not overlap with the side one;
We unscrew the candle on which you plan to perform these actions from its location (or, as an option, take a new one);
Using a glass marker, mark on the desired candle the length to which the side electrode needs to be cut.
We fix the spark plug in a small vice (the main thing is not to overtighten);
Take a grinder (Dremel or any other company) with a cutting disc installed. Carefully shorten the electrode, which is located on the side. The result should be a smooth, parallel cut, not slanting to the sides;

The spark parameters are especially important when the engine is running cold, when the fuel mixture entering the combustion chamber is far from a gaseous state.

A conventional spark plug consists of 2 electrodes separated by a powerful ceramic insulator.

The central electrode is a steel rod, one end of which has a thread for a contact nut, the second is a smooth cylinder located in the discharge zone.

The effective volume of ignition of the mixture is also “sandwiched” by the electrodes.

Small manipulations with the spark plugs will help you make sure that your engine is far from old and can easily run both in the summer heat and in the twenty-degree frost in the harsh winter.

Oddly enough, the service life of such spark plugs increases somewhat as a result of modifications.

for safety reasons, turn off the ground or disconnect the positive terminal of the car from the battery;
disconnect the high-voltage wires and twist the spark plugs that need to be modified;
measure the required length of the side electrode and use a marker or a file to mark the section to be cut off;
we clamp the metal body of the candle in the yew jaws with a force that allows us to ensure its reliable fixation without any damage;
using a hacksaw or cutting disc of an angle grinder, carefully cut off the excess part of the electrode;
carefully process the cut site with a fine file, ensuring an even, straight cut without burrs;
Using round pliers we bend the electrode so that its edge is at the same height as the central electrode, and the air gap corresponds to the passport value;
repeat the above operations on each spark plug;
we screw in the spark plugs and put the caps of high-voltage wires on them;
turn on the ground, ignition and start the engine.

It is precisely this “trick” that allows the fuel mixture entering the cylinders of the internal combustion engine to ignite better and burn more completely.

In conclusion of this article, we can advise you the following. If you don't trust us or are not entirely confident in your abilities, don't worry too much.

You can perform all the operations described on old spark plugs, probably stored in the glove compartment “in reserve.”

The most important thing is that the elements being upgraded are “live” (without shorting the electrodes across the insulator), otherwise you will not succeed.

Good luck!

We clean the place of the cut with a file to remove burrs and irregularities;
Next, set the specified gap. It is different on different brands of cars and trucks, domestic and foreign, turbocharged and not. So, in this case, it is better to navigate through a book or look on the Internet;
A similar procedure must be performed with each candle separately. Then we screw them into place and try to start. I think you should like the effect produced.

What do we have as a result? After the execution, the spark front will increase, and significantly. After all, now the flame is directed directly into the combustion chamber of the fuel mixture. Whereas in a candle, according to standards, the fire is, as it were, sandwiched between the electrodes, side and central. This simple, universal improvement allows the flame to spread more freely, resulting in faster, more complete combustion of gasoline and increased engine power.

Results expected as a result of modification of candles

It is precisely this “trick” that allows the fuel mixture entering the cylinders of the internal combustion engine to ignite better and burn more completely. The simplest modification will allow you to reduce the car’s consumption indicators, increase the power and dynamics of the engine, and by increasing the ignition speed, even slightly reduce its sensitivity to gasoline detonation. In order not to be unfounded, we will say that diagnostic tests of the carburetor engine of a VAZ car on a stand after modification of the spark plugs showed an increase in its initial power within an additional 6-7 horsepower.

Check and doubt

You can check the operation of modernized spark plugs by building a simple stand in the garage from a distributor, a coil and a battery. It will be immediately visible to the naked eye that the spark produced by the spark plug has improved and intensified.

Thus, in fact, the old candle will continue to work efficiently for quite a long time. The only thing that raises some suspicions is: why do some manufacturers continue to produce products that are not finished using this method? And doesn’t such modification of spark plugs with your own hands kill the car’s engine? But, judging by the reviews, there is no particular harm to the engine. But it saves money and fuel resources.

How to modify spark plugs yourself to save fuel

Spark plugs are an essential element of a gasoline engine, creating a spark to ignite the mixture of fuel and air in the combustion chamber. As a rule, the service life of ordinary budget candles is limited to several tens of thousands of kilometers (15-25 thousand), that is, these elements are so-called consumables.

As a result, the engine begins to “pull” worse, the driver presses the gas harder, while more fuel in the cylinders still burns less fully. In other words, there is an increased consumption of gasoline. It is for this reason that many drivers practice modifying spark plugs to save fuel, which we will talk about next.

Read in this article

Why do you need to modify spark plugs?

Let's start with the fact that owners of old gasoline cars, mainly carburetor ones, should modify new spark plugs for good economy and increased power. As a rule, it is on such a dosing system that the issue of gasoline consumption is most acute.

In parallel with this, modifications can have a positive effect on the injector. At the same time, high-tech modern spark plugs with an extended service life (platinum, iridium) should not be modified. It turns out that changes and improvements are most relevant only in relation to ordinary candles. Now let's take a look at the practical benefits of improving candles.

First of all, ease of starting and, as a result, less risk of flooding the spark plugs. This is especially true in winter, when fuel evaporates less easily in a cold engine, the battery charge naturally drops, the oil becomes sticky and the starter turns the engine weaker.
Another advantage that “tuning” spark plugs promises is stable operation of the internal combustion engine in different modes, (especially at maximum loads and high speeds), even taking into account that the composition of the fuel-air mixture will not be optimal, that is, the working mixture is too lean or enriched.
Note that under conditions of high pressure on modified spark plugs, less impact is exerted on the spark, which is simply blown away on a standard spark plug. As a result, the power unit not only starts well, but also burns the fuel charge more fully, delivering more power. This reduces fuel consumption and results in savings.

Do-it-yourself modification of spark plugs

The modernization is based on the task of bringing simple spark plugs closer in a number of parameters to the so-called sports spark plugs. Such products are offered by many well-known manufacturers, but they are significantly more expensive.

Sports spark plugs allow you to increase power and reduce consumption; the declared service life of such elements is 70-90 thousand km. mileage However, in practice, the efficiency of their work decreases, on average, after 15 thousand km, and such spark plugs do not last the entire stated period. Taking into account the high cost, buy these elements every 30-35 thousand km. it turns out to be expensive.

It is for this reason that many drivers do not strive to immediately change a set of spark plugs, since there are ways to extend the life of existing ones. The best way to solve the problem is to modify conventional or sports spark plugs.

The procedure is not complicated, so even beginners can handle it:

to make the spark plug work as efficiently as possible, you will need to shorten the side electrode;
the next step is to correctly adjust the gap on the spark plug;

The whole process looks like this:

Used spark plugs are unscrewed from the engine or prepared in advance (you can work with new elements);
Next, using a marker or another method (for example, a notch is made), a special mark is applied to the side electrode, which will indicate to what length the electrode should then be shortened.
Next, the spark plug is carefully clamped in a vice (preferably with rubber “lips.”) It is important not to overtighten the vice so as not to damage the element.
After this, you will need to take a grinding machine and install a cutting disc;
Use a tool to shorten the side electrode. In this case, it is important to ensure that the cut is smooth, without bevel.
Then the cut site is cleaned with a needle file, nicks are removed, edges are leveled, burrs and other defects are removed.
Now you can start setting the desired gap. The value will depend on the type and model of the internal combustion engine. In this case, it is best to use the manual, get the necessary information on specialized automotive forums, etc.
Shortening the electrode and setting the gap on the spark plugs must be done with each spark plug, and be sure to maintain the highest possible accuracy (how much is cut off from the electrode and what gap is set)
After installing the modified spark plugs on the engine, it is necessary to perform a test run. As a rule, starting should be easier than with conventional spark plugs.
Then you can take a trip, appreciating the stability of operation and improved throttle response of the internal combustion engine, as well as better traction at high speeds.

You can also visually evaluate the performance of the candles. To do this, it will be enough to make a test stand right in the garage. For manufacturing you need to have a distributor, a coil and a power source.

If we talk about the modification itself, the simple manipulations described above make it possible to expand and significantly increase the front of the electric spark. In other words, the spark, after removing part of the electrode, is not sandwiched between two electrodes (side and central), but is immediately directed into the combustion chamber.

As a result, the ignition efficiency of the fuel and air mixture in the engine cylinders improves, and subsequent charge combustion becomes more complete. The dependence of ignition on the quality and intensity of spark formation on the spark plug in relation to the composition of the working mixture is also reduced.

In other words, a more powerful spark more easily ignites a rich or lean mixture to varying degrees, which has a positive effect on the overall performance of the engine under load and in other modes. If the mixture is better ignited by a spark, then the flame front spreads more evenly and freely, gasoline burns fully in the cylinders, power increases, and fuel consumption decreases.

Lada 2107 J7 › Logbook › Refinement of spark plugs

In general, I came across an article that talks about modifying spark plugs by shortening the electrode, supposedly this method has a lot of advantages, from reducing fuel consumption and increasing the life of the spark plugs, to increasing power (the author of the article, after measurements, had an increase of 7 hp!) It became very interesting... Here is the article itself: www.mytyper.ru/talk/topic349.html There are also pictures here for more clarity: race2day.ru/info/garage/%...B0%D0%BD%D0%B8%D1%8F. html For those who are too lazy to click or the traffic on the mobile ends in short: The upper electrode is shortened and the gap is set, everything is clear in the photo below

Thanks to this simple modification we get, I quote: The reduced gap contributes to an easier initial breakdown (1) after which, following the laws of physics, the discharge “slides” along the planes of the electrodes outward, increasing in size (2). As a result, the flame front (3) spreads freely into the combustion chamber, facilitating faster and more complete combustion of the mixture.

I wonder what anyone thinks about this, maybe there are people who have tried this modification personally? Having languidly rummaged through forums on the Internet, I did not find anything significant except opinions and theories of assumptions (underline as necessary). I would really like to get to the truth, to receive reasoned answers to the following questions: 1. Does this make sense? 2. Does such modification damage the engine? I'm waiting for answers) Don't forget to share this post if you, like me, are interested in these questions) Oh yes! Subscribe to my car, a lot of interesting things COMING SOON!

What's the result?

As practice shows, after tuning the spark plugs, engine power, on average, increases by 5-6 hp. These figures were obtained by car owners after testing on a dynamometer. At the same time, the torque increases. Taking into account the simplicity and accessibility of the method, such an increase can be considered quite significant.

We also note that many motorists actively practice this solution. There have been cases where a set of the simplest old spark plugs with a mileage of about 25 thousand km. on bad fuel, after unscrewing from the engine, they were thoroughly cleaned, and then modified using the method described above. After modernization, these spark plugs continued to work normally for at least another 10 thousand km.

Finally, we would like to add that some drivers are skeptical about modernization. The main argument is that candle manufacturers themselves cannot but know about such a simple method of improvement, but still do not introduce it into mass production for some reason. Please note that we will not try to refute this statement.

At the same time, for owners of old cars, it is more important to change spark plugs as rarely as possible, while simultaneously achieving fuel savings, than to monitor a worn-out internal combustion engine with the utmost attention.

Why did the question arise about how to improve spark plugs with your own hands?

Finally, the era has begun when a vehicle is not an excessive luxury, but a means of transportation. Brands of cars from domestic manufacturers are already available at affordable prices, and a secondary car market system has been established, where it is very easy to buy a car second-hand and exchange it for a more budget model. It seems that there are no longer any restrictions and conventions for a person who wants to buy a car. There is a vehicle to suit every pocket.

Spark plug

There are more and more people who are ready to buy a car at an affordable price, and then tune it and modernize it. And this category of people is themselves creative, capable of experimenting, taking decisive steps, and even seriously thinking about how to improve spark plugs with their own hands.

Tuning

Perhaps a used foreign car will not give in in some way, will not allow itself to be remade, but, as they say, nothing is impossible. The structure of domestic machines is more open, and it opens up a wide field for the activity of the imagination. So there are those craftsmen who think about how to improve spark plugs with their own hands. What motivates automobile “Kulibins”, what do they want to achieve?

Experienced experimenters claim that they know exactly how to improve spark plugs with their own hands. When they managed to perform this procedure, that is, bleed the spark plug, they achieved the desired results:

The spark is not blown away by the resulting pressure
All possible engine performance increases almost before our eyes
Gasoline burns completely, so less fuel is consumed.
The machine control system is working properly.

Another reason why some people want to improve the performance of a candle. After all, many people know that its service life is short, lasting an average mileage of 15,000 km, and then you need to monitor its condition, assess whether carbon deposits appear on it, or whether the housing or electrode may even be damaged.

What can happen if you improve your spark plugs yourself?

It is possible to achieve fuel savings. This is the main “engine” of all the actions of innovators who know exactly how to improve spark plugs with their own hands and reduce gasoline costs.
Innovators want to increase the power of the vehicle, thinking that by changing the degree of caviar supply, they will increase the performance of the power unit. An impressive argument for drivers who cannot live without high speeds.
But opponents of the idea of improving spark plugs remind that any design features of a vehicle are driven into its limiting capabilities.
And if you only influence the degree of spark supply and don’t change anything else, then whether progress in implementing the idea is possible or not is still a big question.
You need to solve the question of how to improve spark plugs with your own hands with a cool head and nerves of steel, as well as with a large amount of knowledge and experience in conducting experiments.

Two ways to improve spark plugs with your own hands

Spark plug upgrades are performed only on gasoline engines.
One of the common upgrade options is to shorten the electrode, thus opening up the possibility of adjusting the gap.
The desired result is to shorten the electrode so that the central one does not overlap with the lateral one, but remains dominant. What is the algorithm of actions?
Spark plug electrode

Using a simple marker, mark on the electrode the location of the desired cut off of the part.
Clamps the candle in a vice and continues to adjust the shape of the product.
Using a grinding machine, we cut off the unnecessary segment that was previously marked.
We clean the cut-off area with a file suitable for cutting. The goal is to remove unevenness and roughness, and chips.
We adjust the gap required according to the diagram. The distance depends on the make of the machine and the expected load on it.
All that remains is to return the upgraded spark plug to the standard seat. And start the car, evaluating the result obtained and realizing whether you managed to professionally solve the problem of how to improve spark plugs with your own hands.

What will be achieved during modernization?

After cutting off part of the electrode, the spark front will increase, so the flame will go straight into the combustion chamber. As a result, we should expect complete combustion of gasoline, a small but increase in vehicle power.

The second way to improve spark plugs with your own hands is to carefully bend the electrode, simply forcibly increasing the distance between the components of the spark plug.
Many people resort to this method, but due to lack of skill, the spark plug can be damaged. And remember that you cannot remove a faulty spark plug from the system; it will be very difficult to foresee the consequences. Bend the electrode

Thus, you can determine several answers to the question of how to improve your own spark plugs, and they will be polar.

Firstly, if changes are introduced into the system, the calculations must be verified.

Secondly, you should not push the car beyond its capabilities, because by increasing its power by force, you can actually reduce its service life.

We clean the cut-off area with a file suitable for cutting. The goal is to remove unevenness and roughness, and chips.
We adjust the gap required according to the diagram. The distance depends on the make of the machine and the expected load on it.
All that remains is to return the upgraded spark plug to the standard seat. And start the car, evaluating the result obtained and realizing whether you managed to professionally solve the problem of how to improve spark plugs with your own hands.

The second way to improve spark plugs with your own hands is to carefully bend the electrode, simply forcibly increasing the distance between the components of the spark plug. Many people resort to this method, but due to lack of skill, the spark plug can be damaged. And remember that you cannot remove a faulty spark plug from the system; it will be very difficult to foresee the consequences. Bend back the electrode

Thus, you can determine several answers to the question of how to improve your own spark plugs, and they will be polar. Firstly, if changes are introduced into the system, the calculations must be verified. Secondly, you should not push the car beyond its capabilities, because by increasing its power by force, you can actually reduce its service life.

We would like to know how many car enthusiasts are in favor of improving the spark plug, and who definitely says “no” to such an idea. State your position in the comments, we will be grateful for it.

What will be achieved during modernization?

How to modify spark plugs yourself to save fuel

1 Why do you need to modify spark plugs?
2 Do-it-yourself modification of spark plugs
3 What's the result?

Experienced drivers know well that the stability of engine starting, engine power, fuel consumption and other characteristics directly depend on the quality of spark plugs. It is important to understand that after just a few thousand or even hundreds of kilometers (depending on the general condition of the internal combustion engine, fuel quality, etc.) the spark plugs begin to work less efficiently.

No matter how you look at it in makeshift conditions, you don’t set the same gap for all the spark plugs and the sparks will be different...

(photo of how to check the gap)

It's all billboard! Candle manufacturers are not fools either. I understand that if you wrote that due to the coil, which gives greater voltage, power and duration of spark burning, then such positive effects would result, yes, this is quite logical. But it’s stupid to modify candles with a grinder, it’s stupid. A known good spark plug, with a normally adjusted gap, specifically for your engine, compression ratio, and other crap, is the key to normal engine operation. You can even saw off the side electrode, let it stick to the body, as in formula 1. There is a nickel in the middle, then the insulator, then the rim, and that’s it. And one candle costs 50 thousand bucks. It has an undeniable advantage - the complete absence of glow ignition, due to the heating of the electrodes, they are simply not there! So let's modify all the candles like this))

Why do you need to modify spark plugs?

First of all, ease of starting and, as a result, less risk of flooding the spark plugs. This is especially true in winter, when fuel evaporates less easily in a cold engine, the battery charge naturally drops, the oil becomes sticky and the starter turns the engine weaker.
Another advantage that “tuning” spark plugs promises is stable operation of the internal combustion engine in different modes, (especially at maximum loads and high speeds), even taking into account that the composition of the fuel-air mixture will not be optimal, that is, the working mixture is too lean or enriched.
Note that under conditions of high pressure on modified spark plugs, less impact is exerted on the spark, which is simply blown away on a standard spark plug. As a result, the power unit not only starts well, but also burns the fuel charge more fully, delivering more power. This reduces fuel consumption and results in savings.

Do-it-yourself modification of spark plugs

We also recommend reading the article about which spark plugs are better, iridium or platinum. From this article you will learn about the main differences, advantages and disadvantages of these types of spark plugs.

The procedure is not complicated, so even beginners can handle it:

to make the spark plug work as efficiently as possible, you will need to shorten the side electrode;
the next step is to correctly adjust the gap on the spark plug;

Now let's take a closer look. Regarding the first point, shortening must be done in such a way that the central electrode is not blocked by the side electrode.

The whole process looks like this:

Used spark plugs are unscrewed from the engine or prepared in advance (you can work with new elements);
Next, using a marker or another method (for example, a notch is made), a special mark is applied to the side electrode, which will indicate to what length the electrode should then be shortened.
Next, the spark plug is carefully clamped in a vice (preferably with rubber “lips.”) It is important not to overtighten the vice so as not to damage the element.
After this, you will need to take a grinding machine and install a cutting disc;
Use a tool to shorten the side electrode. In this case, it is important to ensure that the cut is smooth, without bevel.
Then the cut site is cleaned with a needle file, nicks are removed, edges are leveled, burrs and other defects are removed.
Now you can start setting the desired gap. The value will depend on the type and model of the internal combustion engine. In this case, it is best to use the manual, get the necessary information on specialized automotive forums, etc.
Shortening the electrode and setting the gap on the spark plugs must be done with each spark plug, and be sure to maintain the highest possible accuracy (how much is cut off from the electrode and what gap is set)
After installing the modified spark plugs on the engine, it is necessary to perform a test run. As a rule, starting should be easier than with conventional spark plugs.
Then you can take a trip, appreciating the stability of operation and improved throttle response of the internal combustion engine, as well as better traction at high speeds.
You can also visually evaluate the performance of the candles. To do this, it will be enough to make a test stand right in the garage. For manufacturing you need to have a distributor, a coil and a power source.
Next, the usual spark test is performed, which will demonstrate an increase in spark formation, a change in the color of the spark to a bright blue-red, etc. It is optimal to carry out the check in the form of a comparative analysis, that is, compare the spark, its power and color before starting work (on standard spark plugs) and after (on modernized spark plugs).
If we talk about the modification itself, the simple manipulations described above make it possible to expand and significantly increase the front of the electric spark. In other words, the spark, after removing part of the electrode, is not sandwiched between two electrodes (side and central), but is immediately directed into the combustion chamber.
As a result, the ignition efficiency of the fuel and air mixture in the engine cylinders improves, and subsequent charge combustion becomes more complete. The dependence of ignition on the quality and intensity of spark formation on the spark plug in relation to the composition of the working mixture is also reduced.
In other words, a more powerful spark more easily ignites a rich or lean mixture to varying degrees, which has a positive effect on the overall performance of the engine under load and in other modes. If the mixture is better ignited by a spark, then the flame front spreads more evenly and freely, gasoline burns fully in the cylinders, power increases, and fuel consumption decreases.
