Replacing spark plugs for Lada Vesta. Advice from experts, reviews, service life

What kind of spark plugs are installed on Lada Vesta from the factory?

The type of igniters differs in size, depending on the number of valves. In an 8-valve engine the skirt is short, in a 16-valve engine it is long. The standard configuration is from a domestic manufacturer, but nothing prevents the owner from installing imported analogues.

Which spark plugs to choose for Lada Vesta: factory opinion

AvtoVAZ specialists recommend the manufacturer NGK BCPR6ES for both 8-valve and 16-valve engines.

Note to the driver! When replacing spark plugs 16-cl. motor, use a hex wrench set to “14” (it is smaller than for 8-kl).

How to choose spark plugs for Vesta?

Often, car owners do not pay attention to the choice of igniters. Sometimes, in order to save money, old candles that have been cleaned of carbon are used. However, in a modern engine, high-quality ignition devices play an important role.

There are many models of spark plugs for Vesta on the market: conventional and more expensive, high-tech ones (platinum, iridium, multi-electrode). Iridium igniters work stably over a range of up to 60,000 km. If you compare prices, it becomes clear that one iridium unit costs the same as a set of regular ones. In addition, craftsmen and car enthusiasts note that classic single-electronic devices do an excellent job, provided they are replaced in a timely manner. Therefore there is no point in paying more. The main thing is to choose the right type of device.

Here is a list of qualities that candles for Vesta must meet: Uninterrupted operation at voltages up to 40 kV. High thermal conductivity. Resistance to chemical processes and deposits of moderate aggressiveness. Ability to insulate at high temperatures (up to 1,000 °C). Resistance to thermal shock.

Vesta cars are factory equipped with Russian spark plugs AU17DVRM or imported DR15YC-1. In the future, for replacement, you can choose other options from the list recommended by the manufacturer.

So, suitable devices are produced by well-known companies: Bosch, Denso, NGK, Champion. Igniters differ in brand and fundamental technological characteristics. They need to be taken into account when preparing tools for replacing spark plugs.

Eight-valve devices can be dismantled with a regular spark plug wrench. If a replacement is made on sixteen-valve valves, then a smaller hexagon is required.

Features and purpose of spark plugs

Without the spark produced by the igniter, the engine will not start and the combustible mixture will not ignite.

The average life of an original spark plug is 40,000 km or three years, whichever comes first.

The following models are distinguished: conventional, iridium, one-, two-, three-, four-electrode. Iridium ones are 10–15% more expensive than all other types.

The greater the number of electrodes, the greater the likelihood of rapid combustion of the mixture. For domestic cars this is not so important: one electrode is enough.

What spark plugs to install and their price

The Lada Vesta VAZ-21129 engine uses original AU17DVRM spark plugs, where:

Standard domestic spark plugs are just enough for the intended period, but as noted by car owners, after half the service life, difficulties may arise when starting the engine in cold weather. Spark plugs produced by foreign manufacturers will be a worthy replacement:

Bosch - 0242235913. Price per set is 400 rubles. The cost of one such candle 0241235751 is 120 rubles. You can also find it cheaper, of the same brand, only Russian-made Bosch 0242235666 “Super plus” spark plug. Price – 80 rub./piece.

Yttrium F01H7B0146, a kit from this company will cost 220 rubles.

Spark plugs from more famous manufacturers such as Denso , spark plug “Nickel” Q20PRU11 and spark plug from NGK , product code 2330, will cost 100 rubles per piece. Spark plugs from the expensive price segment such as “Longlife” from VAG (made in Germany) product code 101905601F will cost 350 rubles/piece.

Many motorists advise purchasing spark plugs produced using new technologies. These innovations include iridium spark plugs. On the market they are represented by “Iridium Power” spark plugs from Denso, product code IK20TT, price 560 rub./piece.

But installing such expensive spark plugs on a domestic car is simply unprofitable.

What is the difference between spark plugs for 8- and 16-valve engines?

By and large, there are no differences, except for the size of the key that needs to be used to unscrew the case.

New Lada: Advantages and disadvantages of Lada Vesta

“Francecar” fcr20v014 parts are of good quality; this brand is worth paying attention to and it is possible to install it in your car.

Replacing spark plugs on a Lada Vesta with your own hands

Necessary tools, materials

• rags;
• additional lighting (optional);
• a set of new igniters;
• torque wrench;
• hex key for “17”, “14”.

Work progress

1. We wait until the engine cools down. It is prohibited to carry out work when the engine is hot.
2. Open the hood and remove the power terminals from the battery.
3. We remove the plastic decorative trim.

4. Disconnect the coil from the harness connector.

5. Turn the screw securing the coil.

6. We remove the coil from the well.

7. Unscrew the igniter.

8. We insert a new igniter. Tightening torque 25–30 N.m.
9. Screw the coil and put on the block with wires.

In a Lada Vesta car with 8-cl. engine, the replacement process is similar, with the exception of the location of the igniter. The spark plugs are installed on the surface of the cylinder head cover.

Replacing spark plugs on a Lada Vesta with your own hands is completed.

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.

Reviews

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.

Which candles to choose?

We won’t spend a lot of time choosing, for the reasons given above. This is not as important a factor as the timing belt, ball joint, or wheel bearing. Of course, there is one significant nuance. Depending on which engine is installed - 8 or 16 valves. Our spare part for each of them will be special, not universal.
