Spark plugs in a Lada Vesta car...
...designed to ignite the fuel mixture in the cavity of the combustion chamber.
Incorrect operation of one spark plug electrode leads to engine detonation, decreased power, and increased fuel consumption. Since the primary signs of igniter failure are largely identical to other failures, it is difficult for an inexperienced driver to correctly identify the source of the malfunction.
If you do not have the appropriate experience, we recommend that you seek help from mechanics at certified service stations.
What kind of spark plugs are installed on Lada Vesta from the factory?

Note to the driver ! Removal of spark plugs in an 8-valve engine is carried out with a socket wrench (at “19”). For a 16-valve power unit, use a smaller hex key (at “17”).
Features and purpose of spark plugs
The completeness of ignition of the fuel mixture depends on the quality and frequency of voltage supply to the end switches of the spark plug electrodes. Partial combustion of petroleum products contributes to the formation of carbon deposits in the combustion chambers of the cylinders.
Depending on the type of igniter, the following parts are distinguished:
- with copper tip;
- with nickel;
- with platinum, iridium.
Iridium and platinum electrodes have a long service life, but their cost is 20-25% higher than their analogues.
Spark plugs with a copper or nickel tip are the best option for most motorists, as they combine good quality and an affordable price.
Here you can choose spark plugs from 118 rubles per piece.

If the igniter is not working properly, the power unit detonates and shoots in the exhaust system. The vehicle starts moving with difficulty and slowly picks up speed.

In 16-valve power units, the igniters are recessed into the cylinder block body, and in 8-valve power units, they are mounted on the surface of the block cover.
When replacing spark plugs with analogues, be sure to check the consistency of the thread pitch and length. Installing an igniter with a long (short) base contributes to unstable operation of the power unit.

Recommended spark plug kits for Lada Vesta
Many car enthusiasts do not attach much importance to the choice of devices for igniting the combustible mixture. And in vain, in a modern engine they play no less a role than, for example, the timing belt and its performance. It doesn’t hurt to remember here that VAZ offers several engines on Vesta, each of which has its own design features.
Factory recommendations for choosing mixture igniters are similar for all modern AvtoVAZ models. Do not forget to take into account the fact that they are equipped with both eight-valve and sixteen-valve engines. The official data for replacing spark plugs on the new Lada Vesta sedan is as follows.
Conclusion
The stability of engine operation largely depends on the timely replacement of igniters, as well as the quality of their manufacture.

Top 5. BERU Z21 (14R-7DUX)
Rating (2021): 3.94
Ignites lean mixtures. The low heat rating and high conductive characteristics of the materials used in the BERU Z21 spark plug contribute to the reliable operation of the internal combustion engine. Lada Kalina shows excellent dynamics even with a very lean fuel mixture.
- Characteristics
Average price: 144 rub.
- Country: Germany
- Electrode: yttrium
- Gap, mm: 1.1
- Heat number: 7
- Resource, km: 30000
An excellent choice for LADA Kalina owners instead of factory spark plugs. The service life of BERU igniters more than covers the replacement interval recommended by the car manufacturer. The use of the latest developments in the field of conductive materials gives spark plugs the ability to confidently work with very lean mixtures. After installation in a Lada Kalina with a 1.6 liter internal combustion engine with 8 valves, smooth operation at idle and no misfires at high speeds are observed. This has a positive effect on acceleration dynamics. Among the disadvantages - 14R-7DUX is not always on sale; for a planned replacement it is better to order spark plugs in advance.
Advantages and disadvantages
- Quality spark
- Reliable ignition at high speeds
- Not always available in retail
