Representatives of AvtoVAZ assure that the build quality of Vesta is constantly improving. Reviews from owners to some extent confirm this fact. Let's look at how spark plugs behave, among other equipment.
It must be said that Vesta has problems, for example, with not particularly modified wipers, punctures occur with the gas pedal, and there is no corrosion treatment for the bottom. Complaints about deficiencies in power mechanisms are extremely rare. Therefore, it is premature to talk about repairing any element of the fuel system.
Which spark plugs to choose for Lada Vesta: factory opinion
According to Lada Vesta owners, NGK BCPR6ES spark plugs would be an excellent choice.
For an 8-valve engine : 14R-7DU–Ber, RN9Y–Champion, BPR6ES–NGK, W20EPR–Denso, LR15YC-1–Brisk, WR7DCX–Bosch.
For a 16-valve engine : AU17DVRM, DR15YC-1–Brisk, FR7DCU–Bosch, Q20PR-U11–Denso, BCPR6ES–NGK.
The question, of course, is not the name of the manufacturer, but the design features.
The wrong choice of these elements will lead to the fact that they either do not work or will not work.
Denso Q20TT spark plugs.
In addition, for the first option, a regular spark plug wrench is suitable, and for 16-valve models, a reduced size hex wrench is suitable.
Repair procedure
Checking the gap. It should be equal to 1.1 mm
The spark plug gap on the 16-valve Lada Vesta is 1.1 mm.
The process is completely simple if you have the necessary tools. After dismantling, you can assess the presence of a gap between the electrode contacts. Maybe you can just adjust the gap there and there won’t be a need for replacement, but if our 30 thousand kilometers are already behind us, then throw it straight into the trash.
During installation, the engine must be turned off and cooled to ambient temperature.
Spark plug in the engine well.
We will also need a TorxE-8 wrench, 16 head. When replacing an element, it is important to tighten it well, but not excessively, so as not to break the thread. After 30 thousand we will have to repeat the procedure.
One small but important reminder. You need to wrap the candle with your working hand so that you can feel when it goes along the thread. If something happens, you can stop in time by starting the process over again, carefully cleaning the threads. That's all, you can drive until the next replacement.

Features and purpose of spark plugs
Two years have passed since the appearance of the first copy, which means that some of the spare parts responsible for igniting the combustible mixture in the engine cylinders have worn out.
These include spark plugs, which were mentioned in the preamble to this article. To get started, it doesn't hurt to do some background research.
Iridium spark plugs last longer, but are also more expensive.
Without these important elements, the car simply will not move. If the resource runs out, then it is necessary to change the spark plugs. All that remains is to determine how to find out that it is time for replacement. Some characteristic features of the engine indicate this time.
Symptoms of wear
The spark plugs looked absolutely working, but the engine did not work well with them.
- significant loss of power;
- vibration during detonation of the fuel mixture;
- the catalyst overheats due to overload;
- Fuel consumption increases compared to what it was before.
Some car systems may begin to malfunction in unison with the fuel system. The spark plugs are starting to get oily, which means the reflector caps also need refreshing.
What you need to know about Lada Vesta spark plugs
A recent novelty of the domestic automobile industry - Lada Vesta - has become widespread among car enthusiasts.
Despite the fact that the car has been in production for only a few years, owners are gradually beginning to encounter minor problems and periodic maintenance, which includes replacing spark plugs on Lada Vesta cars.
This need is not a shortcoming of the machine or a serious breakdown; timely replacement of small spare parts will help in the future to avoid major repairs of the main moving parts.
Features and purpose of spark plugs on a Lada Vesta car
Plugs are one of the most important components in the ignition system of any car; without them, it simply will not start. Using a discharge on the electrodes, the flammable fuel-air mixture is ignited. Engine power, efficiency and even toxicity of exhaust gases depend on the stable operation of igniters.
Lada Vesta cars produced from the factory can have two types of spark plugs:
- AU17DVRM (Russia);
- Brisk Super DR15YC-1 (Czech Republic).
Both of these models of ignition elements, according to reviews from car owners, have proven themselves well, they last well and do not cause problems.
Signs of wear
It is usually recommended to replace the spark plugs after the vehicle has traveled a certain number of kilometers. It is not advisable to allow the wear of these elements to affect the operation of the engine and the entire ignition system.
But, if the igniters were not replaced in time, or the new ones turned out to be defective, then obvious signs of their malfunction will, first of all, affect the operation of the engine. The first sign is that the engine has become difficult to start and does not pull.
It may also trip or jerk and lose power. Sometimes wear of the ignition elements provokes increased gasoline consumption, as well as poor performance and overheating of the catalyst.
If traces of oil are found on the spark plugs themselves or the threads, this is a clear sign that the reflector caps also need to be replaced.
Regulations for replacing spark plugs on Lada Vesta
16 valves under the hood of Vesta.
When the critical time has come, the first question is what elements are best to use so that it lasts longer and the work is more or less satisfactory. In order to ignite the combustible mixture of atmospheric engines, an electrical discharge of tens of thousands of volts is required. For this we need decent specimens.
According to recommendations, spark plugs need to be changed every 30 thousand mileage.
In fact, it turns out that the potential of the spare part is much greater, presumably by another 100%. Problems with the quality of fuels and lubricants and other nuances prevent the operation of mechanisms under conditions close to ideal. For this reason, 30 thousand is a good number that should not be neglected.

Characteristics of candles
Spark plugs for 8 and 16 valve engines are different.
The service life of candles does not particularly depend on the manufacturer, since we are not talking about stuffed technological equipment. In our case, this is a piece of metal of the correct shape with dielectric elements of the body. If the spare part meets certain requirements, then there is no need to fool your head.
Main characteristics:
- They should not lose their insulating properties at temperatures of a thousand degrees;
- Without interruption, they must provide a stable voltage of 40 kilovolts;
- Resistance to thermal shock;
- The metal must withstand chemical reactions at the installation site;
- The thermal conductivity of electrodes and insulators must comply with the standards.
When replacing, visually compare the old and new spark plugs.
Denso iridium spark plugs
Many owners of Lada Vesta choose the appropriate ignition elements made of iridium. In theory, spark plugs made from this material help reduce fuel consumption, have a beneficial effect on the life of the catalyst, and also guarantee high-quality operation at any speed.
Although, judging by the reviews of car owners, iridium spark plugs have no significant advantages. Basically, it is enough that these candles meet the necessary requirements: resistance to high temperatures (up to 1000 degrees Celsius), inertness to substances resulting from chemical reactions during fuel combustion, resistance to thermal shock, and have sufficient thermal conductivity in accordance with standards , provide a voltage of 40 kV.
Ignition elements are sold in ordinary auto parts stores. Copper candles are the most common; they are almost always available in the store. Models from other brands usually need to wait, or can be ordered online. You just need to find what you need, order delivery, and pay either in advance or upon receipt. In online stores, prices are much more reasonable than in retail.
Main characteristics of spark plugs:
- must withstand high temperatures (up to 1000 degrees);
- operate at a voltage of 40 kV;
- resistance to substances formed during reactions during fuel combustion;
- resistance to thermal shock;
- thermal conductivity indicators must be in accordance with standards.
