Which NGK spark plugs are suitable for VAZ 2114

Every gasoline engine vehicle requires spark plugs to operate. Plugs, along with fuel, ensure the reliability and uniformity of operation of the entire power plant; if the spark plugs reach their service life, various interruptions in the operation of the engine may occur, including stopping.

This article talks about the spark plugs used in the VAZ 2114 car, namely about their timing and replacement methods, gaps and brands that are perfect for the engine of the “fourteenth” Lada model.

After studying this article you will find a lot of interesting and useful information about choosing spark plugs for your car.

What is a candle for?

Spark plugs in a car are one of the main elements of the ignition system. It is the spark plugs that ignite the fuel mixture while it is being compressed by the piston. When the fuel in the combustion chamber is compressed, the spark plug produces a spark, thereby igniting the mixture.

The spark on the spark plug appears under the influence of high voltage generated from the ignition module. The voltage on the spark plug can reach several tens of kilovolts, which is a lot. For example, in a household outlet there is only 220V. Therefore, due to the high voltage, touching high-voltage wires while the car engine is running is PROHIBITED.

Spark plug manufacturers

Below, we will present each spark plug manufacturer separately to make it easier for you to choose.

• Spark plugs A-17DVRM Engels - spark plugs from this particular manufacturer are installed directly from the factory and have a service life of 30 thousand kilometers.
  In general, they more than earn their value, however, judging by the reviews, sometimes there are defects among them, so before purchasing them, it is best to check them. Candles that are installed directly from the factory.

• Brisk candles , Czech Republic - candles that are in great demand among car owners, because they have proven themselves only from the best side. The gap of the BRISK SUPER FORTE LOR15YC-1 is only 1.1 mm, so they are able to show, if not the best, then a fairly good result.
  Reliable spark plugs that have proven themselves in operation.

• DENSO spark plugs - The Japanese brand of spark plugs does not need any introduction, because the quality of these products has always been at their best. Numerous customer reviews speak for themselves, noting, among others, the DENSO W20TT and W20EPR-U11 that are ideal for the VAZ-2114.
  Optimal price-quality ratio.

• NGK spark plugs are one of the most popular companies used by VAZ-2114 owners. NGK No. 13 BPR6ES-11 is exactly the spark plug model that is suitable for the “fourteenth”, and as the owners say, it works successfully even after 35 thousand kilometers.
  Spark plug

Before buying spark plugs, ask the seller to check them on a special stand for the presence of a spark and no breakdowns.

1. Normal candle.

Brown or grayish-yellow color and slight wear on the electrodes. Accurate thermal value for engine and operating conditions.

2. Soot deposits.

Dry soot deposits indicate a rich air/fuel mixture or late ignition. Causes misfire, difficult engine starting and unstable engine operation. Check if the air filter is clogged and if the coolant and incoming air temperature sensors are working properly.

3. Oil deposits.

Oily electrodes and spark plug insulator. The reason is oil getting into the combustion chamber. Oil enters the combustion chamber through valve guides or piston rings. Causes difficult starting, cylinder misfires and jerking of the running engine. Repair of the cylinder head and piston group of the engine is required. Replace spark plugs.

4. Overheating.

The following reasons are possible: the type of spark plug does not match the one recommended for your car’s engine, early ignition, lean mixture, air leaks into the intake manifold. Check the coolant level and whether the radiator is clogged.

5. Early ignition.

Melted electrodes. The insulator is white, but may be contaminated due to missed sparks and deposits from the combustion chamber falling on it. May cause engine damage. It is necessary to check the correct type of spark plug, serviceability of the knock sensor, cleanliness of the injector nozzles and fuel filter, operation of the cooling and lubrication systems.

6. Glaze.

The insulator is yellowish, covered with glaze. Indicates that the temperature in the combustion chamber suddenly rises during sudden acceleration of the vehicle. Normal deposits become conductive. Causes misfires at high speeds.

7. Bridge between electrodes.

Deposits from the combustion chamber fall between the electrodes. “Heavy” deposits collect in the gap between the electrodes and form a bridge. The spark plug stops working and the cylinder stops working. Identify the faulty spark plug and remove deposits between the electrodes.

8. Ash deposits.

Light brown deposits crusting over the center and side electrodes. Isolated from additives to oil or gasoline. A large number of them can lead to insulation of the spark plug electrodes and cause gaps in spark formation and interruptions during acceleration. If excessive deposits form over a short period of time or low mileage, replace the valve guide seals to prevent oil from entering the combustion chamber.

9. Wear.

Rounded electrodes with a small amount of deposits on the working ends. Normal color. Causes difficult starting in cold or wet weather and reduces fuel efficiency. Replace the spark plugs with new ones of the same specifications.

10. Detonation.

The insulator may be cracked or chipped. This may damage the piston. Make sure that the octane number of gasoline matches the required one. Check the serviceability of the knock sensor.

11. Spotted deposits.

After proper adjustment, carbon deposits deposited in the combustion chamber begin to burn out; at high engine speeds, it comes off the piston and sticks to the spark plug insulator, causing occasional misfires in its operation. Replace the spark plugs with new ones or clean the old ones.

12. Mechanical damage.

Damage can be caused by foreign objects getting into the combustion chamber, and if you use a spark plug that is too long, its electrodes can catch on the piston. This causes spark plug destruction, cylinder shutdown and can damage the piston. Remove the foreign object from the cylinder and/or replace the spark plug.

Welcome! Spark plugs - in all frets there are only four of them, in some cars high-voltage wires coming from the distributor are connected to them (Carburetor cars), in some cars these wires are also connected to them, but coming from the ignition module (Injection 8 valve engines) and in some there are no high-voltage wires at all, and instead of them there is one ignition coil for each spark plug (these are 16 valve engines), usually difficulties arise with such engines, the owners sometimes have no idea how to change spark plugs in such an engine, but this is done very easily and in this article we will teach you how to do this in every engine that was installed on the Samara 2 family, and as you know, quite a few engines were installed on them, starting from an 8-valve carburetor and ending with a 16-valve engine with a distributed injection system (In other words, an injector).

Note! To carry out work on replacing spark plugs in an engine, you will need: Be sure to have a spark plug wrench (When you buy it, tell the seller for which engine you are buying the key for, because on 16 valve engines, the spark plug wrench comes with a completely different and different type), and so A screwdriver and a wrench can also come in handy in order to remove the negative terminal from the battery, thereby protecting yourself and the car from a short circuit!

Summary:

Where are the spark plugs located? If you have an 8 valve engine, then the spark plugs are located in the side of the cylinder block and they are screwed straight into the combustion chamber, see the second photo below for more details, in 16 valve engines everything is a little different, no wires as we already said to the spark plugs does not work, you will need to immediately look for coils there (All four coils are indicated by arrows in photo 1), under these coils there are spark plugs that must be replaced from time to time.

When should you change spark plugs? It all depends on the operation of the engine, if the engine is very worn out or if the ignition is set incorrectly and detonation occurs from time to time, then in this case the spark plugs are much more likely to be replaced, or during detonation they are destroyed (What is detonation, read the article: “Detonation that occurs over time from time in a car engine") and by the way, it will no longer be possible to restore them, unlike if the engine runs normally and without interruptions, just when everything works ideally, a coating forms on the spark plugs only from time to time, which can be removed by sandblasting and then the spark plugs will be like new, if you live in a big city then search on the Internet, maybe someone is doing this for a very low price, after sandblasting the spark plug it will literally be like new and it can still be used in your car for a long time.

Note! The frequency of replacing spark plugs is about 10-20 thousand km. If they are clogged, the car will obviously drive worse, and it will also be difficult to start in cold weather (the spark will be weak) and most importantly, due to severely worn spark plugs, the car may get up and not go anywhere else, as a rule, this is a rare case, you just change them on time and everything will be fine, but the fact that there is no spark on the spark plugs can be due to various factors in which either the ignition system or the module is to blame, or one of the four coils!

Signs of faulty spark plugs

Signs of faulty spark plugs can include many different factors, which will be similar to problems in the fuel supply, problems with the ignition module and high-voltage wires.

It is necessary to check the spark plugs if the following signs of malfunction appear on your car:

• The engine is running rough (one of the cylinders is not working);
• The car's dynamics disappeared;
• Difficulty starting the engine;
• Fuel consumption has increased;

Checking the spark plugs

Checking spark plugs is quite simple; their condition can even be assessed visually. To do this, just unscrew the spark plugs and check their condition and compare them with the picture below.

Even if the spark plug is externally in excellent condition, this does not mean that it is working properly. To definitely ensure that the spark plug is working properly, you need to replace it with a new one or swap it with a spark plug from another cylinder. If this spark plug does not work on another cylinder, then there is a breakdown in it, and if the spark plug starts working, then most likely the problem is not in the spark plug.

Gap on spark plugs VAZ 2114

One of the most important parameters in a spark plug is the gap between its contacts. This gap affects the formation of a spark at the contacts; the smaller the gap, the stronger and faster the spark; the larger, the weaker.

On VAZ 2114 engines, spark plugs must have a gap of 1 mm. This gap is optimal for proper and reliable operation of the engine.

Which spark plugs are best for the VAZ-2114 (survey)?

Today, the choice of spark plugs is very large, and choosing the ones that need to be installed is not so easy. On most forums, owners of VAZ-2114 cars are most often advised, “Finwhale” “Champion” “Brisk Premium” “Bosch Platinum”, “DENSO”.

Remember that the best spark and the greatest amount of heat will be given by the spark plug that has the thinnest electrode, 0.4-0.8 mm in size, and they are usually made from alloys of iridium, platinum, palladium and gold.

Also, the situation with a spark that has a coating of platinum, silver or gold on its body has the best effect. For comparison, the “stock” spark plug from DVRM has a thickness of 2.5 mm, while on imported analogues it barely exceeds 0.6-0.8 mm, so there is no point in talking about any competition here.

Replacing spark plugs

Useful video on replacing spark plugs on a VAZ 2114
To replace spark plugs on a car, you do not need a higher education as a car mechanic, you just need to have spark plug wrenches and a new set of spark plugs.

• Remove the spark plug wires from each spark plug;
• Unscrew the spark plugs using a spark plug wrench;
• We screw in new spark plugs and put on the wires;

The spark plugs have been replaced, as you can see, there is nothing complicated about it. Be careful to connect high-voltage wires in a strict order, from left to right. Incorrect connection of the wires may make it impossible to start the internal combustion engine.
