Types and characteristics of spark plugs

There are several types of spark plugs. First of all, the elements are classified depending on the dimensions of the hex key:

SZ turnkey 16 mm;
SZ turnkey 21 mm.

The length of the threaded part is 19 and 26.5 mm, respectively.

In addition, these elements are distinguished by length and thread pitch. Depending on these parameters, SZ are 10, 12, 14 and 18 mm, the thread pitch of which is 1.25.

One of the main parameters for candles is the heat rating. In this case, its indicator is seventeen. It is this parameter of the product that allows the part to withstand glow ignition, which causes engine detonation, which causes its breakdown.

Spark plug heat number

According to the heat index, spark plugs are classified as follows:

cold – above 20;
average – from 16 to 19;
hot – from 11 to 14.

Thus, only medium SZ should be installed in Lada Granta cars. The use of cold elements leads to problems with starting the engine, and hot elements lead to detonation and, as a consequence, engine failure.

Attention! In some systems, the heat indicator may have different numbers. The main thing is that it is average.

Hammer F6TC

Price: from 145 rubles.

Hammer F6TC are inexpensive spark plugs with one side electrode and a high-quality seal in the form of a flat gasket. Suitable for installation in domestic cars, as well as some foreign cars.

Pros:

low cost;
good workmanship;
convenient installation in the engine;
versatility of use;
ease of replacement.

Minuses:

some copies quickly fail.

What kind of spark plugs are installed at the factory?

At the manufacturer's factory, spark plugs are installed in the engine, the heat value of which is seventeen. The manufacturer recommends that vehicle owners install products with this indicator in the future.

If we talk about which spark plug manufacturer AvtoVAZ prefers, then there is no clear preference. Different conveyors use different models.

However, most car enthusiasts claim that they purchased a car with A17DVRM spark plugs from the Saratov manufacturer ZAZS OJSC.

Rules for replacing spare parts

When replacing spark plugs, you should not rely on the mileage of the vehicle. The fact is that one part can withstand 100,000 km, while the other cannot withstand 20,000. This indicator depends both on the condition of the engine and on the spark plug itself. For this reason, there is no exact data on at what stage of a car’s mileage it is better to change these parts.

Experienced Lada Granta vehicle owners recommend performing the appropriate manipulations after the second oil change. The fact is that low-quality fuels and lubricants can lead to premature wear of parts. In addition, no one is safe from purchasing counterfeit candles instead of original ones. For this reason, it is best to play it safe and change the corresponding elements after every second oil change.

In addition, it is recommended to perform the procedure earlier than the specified time if the following problems occur:

long rotation of the starter when starting the engine;
the engine does not start or starts after a long delay;
when the car is warming up or moving in neutral gear, uncharacteristic engine sounds occur;
increased gasoline consumption;
if you unscrew the spark plugs, they will be wet or filled with gasoline;
a decrease in car engine power, which becomes especially noticeable when the vehicle moves uphill.

What does carbon deposits on NW indicate?

If a light brown soot appears on the NW, then there is no reason to worry. This is a normal process and does not indicate any failure. If the deposit has a different shade, then this indicates a malfunction. By its color you can determine what exactly happened:

red and white soot indicates the use of low-quality gasoline;
black tint indicates leakage of lubricants;
loose soot of a dark shade indicates the need to change fuels and lubricants;
an oily coating indicates that lubricant has entered the combustion chamber;
a red tint of soot may indicate a breakdown of the gas converter;
an ashen color indicates problems with the valve stem seals.

Attention! If the spark plugs have not only plaque, but also any damage, then it is recommended to replace them.

Let's sum it up

Taking into account the above information, it becomes clear that choosing Lada Granta spark plugs for an 8-valve engine is quite simple. You can use both original solutions supplied by the manufacturer and analogues from other manufacturers.

The main thing is to choose the spark plugs correctly, that is, taking into account the basic parameters for an internal combustion engine of this type (heat rating, physical dimensions, etc.). It is also important to buy spark plugs from trusted sellers to eliminate the possibility of purchasing a fake.

We also recommend reading the article on how to determine the condition of the engine by spark plugs. From this article you will learn how to diagnose an engine using spark plugs, as well as what nuances you should pay attention to as part of such a check of the condition and quality of operation of the power unit.

Finally, we note that the above basic rules and recommendations are also relevant for many other cars with a similar type of engine (for example, selecting Grant 16 valve spark plugs and replacing them.) Only the parameters of the spark plugs themselves will differ, and there may also be some individual nuances in terms of replacement on a motor of one type or another.

Spark plug replacement procedure

To change spark plugs correctly, you need to proceed as follows:

Turn off the car engine and wait until it cools down.
Remove the cap СЗ and move it to the side.

Remove the SZ cap and move it to the side
Take a clean piece of cloth or a brush and carefully brush the area around the element you are replacing.

Cleaning from burning

If necessary, the working surface of the part is cleaned of burning. Do not use sharp metal objects (screwdriver, awl, scalpel) to avoid damaging the insulator. Fine sandpaper is suitable for removing carbon deposits. You can clean the electrodes thermally or chemically. Inspection is carried out every 10 thousand km of the vehicle. If the intensity of vehicle operation is low, maintenance should be carried out 2 times a year: before winter and summer.

Replacing a spare part with a new one does not guarantee its high-quality and reliable operation. The same goes for spark plugs. No one can guarantee that a new spark plug will withstand 30 thousand kilometers. Based on observations of the engine’s operation, the driver makes a decision about replacement. According to the recommendations of experts, it is necessary to change spark plugs in the following cases:

The car doesn't start well.
Gasoline consumption increases significantly.
Troubles the engine.
Engine thrust and power are reduced.
Mileage is more than recommended.

On the Lada Granta, high voltage is supplied to the armored wires. Please remember that contact with the coil wires will result in electric shock.

Maintenance of the ignition system and timely replacement of spark plugs will reduce fuel costs and reduce the risk of vehicle failures.

Automotive spark plugs, also known as spark plugs, are essential for igniting the mixture of gasoline and compressed gas in the engine cylinder. The voltage on the electrodes of individual spark plugs can reach up to 30 thousand volts, their operating temperature sometimes exceeds 1000 degrees Celsius, and the pressure in the combustion chamber reaches 100 bar. Their operating conditions are constantly changing, so they instantly find themselves at the center of the explosion, and they are soon quickly cooled by the cold air sucked into the cylinder. In this article you will find out which spark plugs are best for the Lada Granta 8 valve.

Rules for choosing candles

When choosing a SZ, you should focus on such points as:

turnkey dimensions;
potassium number indicator: the optimal option is 17, but other values are acceptable, the main thing is that the potassium value is average;
distance between electrodes - in this case it is best to choose spark plugs with a gap of up to 1 mm;
thread dimensions;
type of electrodes - it is best to give preference to nickel elements.

So which spark plugs should you choose for a Lada Granta with an 8-valve engine? When purchasing, it is recommended to take into account the specified characteristics, as well as the manufacturer and cost of spare parts. So, if you need inexpensive spark plugs, which are most often installed in cars at the factory, pay attention to the Bosch Group model, A17DVRM 0.7 4 pcs. Among the budget elements, we can also recommend the Lada-Image ZAO 21110370701000 option. If the price does not matter to you and you require SZ with a long service life, take a closer look at the NGK 4919 BCPR6EIX-11 model.

Gap adjustment

Spark plug maintenance involves cleaning and adjusting the spark gap between the electrodes. It must be taken into account that it increases to the maximum permissible distance. During operation, metal parts wear out. The central straight electrode is rounded, and a depression is formed on the side curved plate. To prevent interruptions in spark formation, it is necessary to adjust the size of the spark gap. It is set with a probe within 1-1.5 mm. The feeler plate fits flush into the correctly set gap.

Reviews

I prefer to use "Japs". I recently changed it on my Grant after 45 thousand mileage! Their quality is excellent and their service life is impressive (if, of course, you drive carefully and regularly clean and check their condition). Vladimir Ivanovich

I have used Ladas my entire automotive life and installed BRISK spark plugs on them. And it pulls well and is reliable. But, really, you need to check it regularly and change it after about 25,000 miles - then the engine works well and without any whims. Sergey

And I love domestic producers. Is it worth supporting him? But here it’s true that you don’t have to do it once at a time, and I travel a lot. Once I came across a perfect piece of shit... I even had to return it to the seller at the market and exchange it for another set. Everything turned out to be ok with the replaced one - I installed it and drove off. Semyon
