Auto Lada

Despite the fact that most people like foreign cars, some people only support the domestic auto industry. The Lada Granta is a good, one might even say reliable, car, but for it to really be that way, it is important to constantly take care of the vehicle. Most experienced drivers cope with this task with 5 points, but beginners encounter problems. One of the common ones is unstable engine operation, which is caused by bad spark plugs.

The editors of the YaNashla website have prepared for you a rating of the best spark plugs for Lada Granta for 2022.

Clean or replace completely

Many motorists prefer not to change spark plugs, but simply clean them. It’s okay if this is carried out in a professional workshop using special equipment. But most beginners cleanse only with home tools.

According to the recommendation of experts, replacement should be carried out almost every 30 thousand kilometers. Of course, this value is typical only for ideal conditions. In practice, the situation can be much worse. So the user will need to replace the spark plugs prematurely if he finds the following problems:

When starting the engine, the starter starts spinning much longer than usual, often the problem may not be noticeable at an early stage, but then the duration increases.
If a person overheats the engine or moves at neutral speed, the engine begins to make strange sounds, while there were none before. This also indicates that attention needs to be paid to this element.
Increased gasoline consumption.
The engine has become less powerful. This is quite easy to check; a person only needs to drive up the hill, the difference will be obvious.
The last sign that the element needs to be replaced is when unscrewing it, it is discovered that the element is too wet due to gasoline and wiping does not help in any way to eliminate the problem, since after a few kilometers the spark plugs are wet again.

If a person encounters one of the listed problems, it is recommended to contact the service or change it yourself.

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

When to clean

But replacement will not be required in all cases; some problems can be solved by simply cleaning the element. This should be done especially for those who detect a large amount of soot. In addition, the color of the coating indicates certain engine problems. Often, it is by the shade of soot that experienced specialists determine the cause of the breakdown. For example:

A brown coating indicates that there has been slight wear on the electrodes. There is nothing wrong with this, because the spark plug and motor are in completely good condition.
Black tint, velvety structure, a small amount of soot is present. The appearance of this color can be caused by two reasons: late ignition or problems with the air-fuel mixture. To make sure there are no serious problems, you should check the air filter and DTOZH. This will help to accurately determine what caused the formation of such a shade.
An oily coating often appears due to lubricant entering the combustion chamber. The reason for the penetration of this substance is the wear of caps, valve bushings, etc. If you find a problem, you should fix it immediately to avoid any trouble.
Soot of a reddish hue. This color indicates that the exhaust gas converter is broken. But everything will not necessarily be exactly like this, because the formation of reddish soot is often associated with the presence of anti-knock additives contained in gasoline.
Soot is white. There may be two reasons for the formation of such a deposit - the person used low-quality fuel, or the ignition parameters were set incorrectly.
The last shade is ashen. Most experts are inclined to believe that such deposits appear due to problems in the valve stem seals.

Black, brown and white carbon deposits will not cause any problems for the user; all you need to do is clean the elements and install them in their original place. But if the driver discovers an oily or reddish coating, this element should definitely be changed. The same applies to the last point, but if you don’t have the necessary magazine at hand, you can temporarily ride on old ones, but before that you need to clean 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.

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.

Right choice

The car manufacturer recommends installing only single-electrode spark plugs. This is expressly stated in the instruction manual. So, for an 8-valve engine, a good solution would be a product that is marked A17DVRM; for another engine with 16 valves, you need to select another product: AU17DVRM.

In addition, if a person does not trust Russian spark plugs, foreign analogues can be used. However, it is important to take into account some subtleties in order to choose only the right option.

Replacing spark plugs is one of the activities that can be carried out by anyone, even those who rarely open the hood. All you need are tools and 30 minutes of free time. Before proceeding with replacement, it is necessary to remove old spark plugs where obvious damage has been identified.

On purchased products, a person will need to set the optimal gap. The permissible value is 1.1 mm, with an error of 0.4 mm allowed. In order for the parameters to correspond to reality, you need to use a special probe; it is sold in almost every car store.

When purchasing a new Lada Granta, you need to change the spark plugs every 30,000 km, but if any problem is discovered (which happens often), you will need to immediately install new elements.

The engine itself will tell you that the spark plugs need to be serviced or replaced. For example, it will take longer to start, and strange jerks occur while the engine is running. Experienced specialists often hear the sound of cylinders working unevenly, which also indicates problems with the spark plug.

How to replace spark plugs

Before installing a new product and removing failed spare parts, you must disconnect the negative pole of the battery, which, unlike the positive one, is black and has a “-” symbol. The cost of replacing the device is very low, starting from 150 rubles each. The cost will increase or decrease depending on the volume and number of cylinders.

On average, gasoline vehicles are serviced every 60,000 km. However, depending on how intensively the car is used, this interval may be shorter and the glow system will fail between 35,000 and 40,000 km.

Remember that if only one spark plug is faulty, it is advisable to replace them all at once. Below we provide step-by-step instructions necessary for installing the equipment:

a wrench of a certain width so that you can unscrew and secure the new device;
ratchet or hexagonal head to facilitate removal of the product;
a compressor with compressed air to thoroughly clean all openings and connections;
goggles to protect your eyes from debris that may bounce off during blowing;
You need to put gloves on your hands, they will come in handy when working with cables.

1. First of all, keep in mind that the engine must be cold, you need to start working after 2 hours from the moment of using the equipment. The spark plugs are usually visible or under a plastic protector. They have a characteristic shape that will be very easy to find.

2. Disconnect the high-voltage cable from the required plug, carefully pulling it towards the top so as not to damage it. Do this carefully, remembering the location of all the wires so that you can then secure everything in its place.

3. Remove the fork and spool using a hex wrench, appropriate ratchet, or wrench. To remove the device, you need to turn the tool counterclockwise.

4. Then blow out the mounting hole, completely clearing it of dirt. It is important to wear safety glasses when doing this.

5. Secure the new product. Lubricate it and start screwing it in carefully by hand, applying a little force, then use a wrench to tighten the device, being careful not to overdo it too much.

6. Insert the ignition coil, tightening it with the screws and ratchet you used earlier. Be careful not to apply too much pressure as this may damage the threads and the reel itself.

7. Connect the cable and repeat the same process for each design.

If you did everything correctly, used the appropriate key size, unscrewing the heads, the car will start and work more efficiently.

Varieties and features

When purchasing spark plugs, you will need to pay attention to the material used to make the electrodes, as well as their quantity. Because not all motors will require the use of single-electrode models.

Based on the number of electrodes, products are divided into several varieties, among which the following models are popular:

Two-electrode. The product is equipped with a central and side electrode. The product belongs to the classic models, as it is installed in most vehicles. During startup, a spark is formed between the two electrodes, which ignites the fuel mixture.
Multi-electrode versions are also available. The peculiarity of this option is the presence of more than two side electrodes. The principle of operation is practically no different from the previous copy. However, most people like this design because of its reliability and stable operation.
The latest model is plasma-prechamber. A similar element appeared not so long ago, about 20 years ago. At the same time, most specialists cannot understand the meaning of the invention of this product; of course, there are differences from the traditional element, but they cannot be called too significant. The main feature of the design is that the spark plug body acts as a side electrode; for this purpose it is equipped with a heat-resistant nozzle, thanks to its action a spark is formed.

Despite all the improvements that companies are making, most buyers still prefer to purchase only classic candles that have a standard electrode.

About aspects of the ignition system

In the engine compartment of the Lada Grant there is a 1.6-liter 4-cylinder engine, the design feature of which is the presence of both an 8-valve cylinder head and its 16-valve version. Depending on the type of valve mechanism used, the power indicator is equal to 82 hp. With. or to 106 “forces” respectively.

The control module is designed to monitor the correct functionality of the ignition circuit. This device receives certain impulses sent by sensors and processes them. The ECU then generates a voltage that is subsequently addressed to the coils.

For different valve mechanisms, the coils have their own design and location configuration. So in 16-valve variations of LADA Granta engines, these components are located in separate wells, the number of which is “4” (according to the number of cylinders).

For 8-valve units, the manufacturer used a single-casing design, which is essentially a step-up transformer. This device is equipped with a single primary winding with a middle location of its output and two secondary ones, whose output contacts are connected to spark plug tips. The ignition circuit of the Lada Granta, which has an 8-valve timing unit, has a so-called “idle” spark method. The essence of the declared technology lies in the synchronous generation of a spark in two cylinders at once. In the first of them (conditionally) it ignites the mixture and is considered “working”, and in the other it “skips in idle mode”.

Electrode material

Also, when purchasing spark plugs, you need to pay attention to the material from which the electrodes are made. Several solutions can be used for these purposes.

Copper/Nickel

The main advantage of this option is low price and good efficiency. Here you can argue about the performance parameters, which are rarely distinguished by high performance, however, given the price segment in which the candles are sold, this is one of the best options. They will definitely last for 20,000 km, after which it is better to immediately change them to new spark plugs.

Platinum copies

The peculiarity of this electrode is that it is coated with precious metal. Thanks to this solution, the service life is increased and the quality characteristics are improved. When installing such a spark plug, a person may forget about replacing it for the next 50,000 kilometers. However, after the expiration date, the element will need to be replaced immediately.

Also, instead of platinum, any other coatings can be used. Not to say that technically the performance will become worse.

Iridium

The main feature of this product is its service life, which is 100 thousand kilometers. In addition, the product has the best technical performance and guarantees reliability to every driver. The only drawback is the high cost, which almost immediately discourages the desire to purchase such candles.

Comparison with competitors

Strict quality control and leading positioning in the global market allow Denso spark plugs to be considered one of the favorites when choosing a new set - indeed, in most cases, in terms of price/quality ratio, they will beat their analogues. If the car initially uses iridium spark plugs, especially with a rare shank size (for example, 10x19), then in fact the choice remains only between Denso and NGK. In this case, sympathies may also be on the side of Denso, since their range allows you to choose a more suitable type of spark plug - long-lived Iridium Tough, highly efficient Iridium TT or Iridium Racing, if you plan to squeeze everything out of the engine that it is capable of.

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

AvtoVAZ supplies, and recommends to us, the installation of spark plugs with an average heat rating of 17 . As for the manufacturer, there is no single answer, since candle suppliers may be different on different conveyors. Most often, Grants with 8-valve engines are equipped with standard Saratov spark plugs A17DVRM produced by ZAZS OJSC. There, at , they produce their analogues WR7DCX with the BOSCH , but they are, naturally, more expensive.
