Rating of the best spark plugs for Lada Granta, Priora and Kalina in 2022

Spark plugs are in any gasoline engine, because they generate the necessary spark, causing the ignition of the air-gasoline mixture, which then enters the cylinders through the valve and sets the car in motion.

Due to the harsh conditions to which they are exposed, high temperatures, pressures, vibrations, products wear out quickly, especially contacts, which are key elements of the device. The more powerful, faster the generated spark, the more efficient the start, the wear of the remaining components of the electrical network and the battery is minimized.

In our review, we will provide recommendations: what to look for in order not to make a mistake when choosing a product, which company model is better to buy. We will get acquainted with popular manufacturers, a description of the ignition systems for the Lada Grant, Priora and Kalina, we will orient you at an average price.

Types of candles, their device

Not enough horsepower during acceleration, slow start, fuel consumption is growing at a gigantic pace, the car is shaking? You need to look at the heating system. These failures can occur for other reasons, but they are the clearest sign that the ignition is not working properly. Depending on the number of cylinders of the car, the number of candles changes. Consider the components of the system design, their functionality:

• upper terminal: connection point of the ignition coil;
• main body: high voltage generation and heat insulator;
• thread: screwing the product into the cylinder head;
• electrode: the source of the spark, the most important element, the quality of the system depends on its reliability.

It is important to know the difference between the two existing types of glow systems - spark plugs and glow plugs. The former are used by vehicles with a gasoline engine, and the latter by vehicles with a diesel engine. A standard feature of both options is assistance when starting the engine. Here are some of the main characteristics of the system:

• material of the central contact;
• the size of the spark gap;
• incandescent number (the larger it is, the less the product heats up);
• overall and connecting dimensions (length and thread pitch);
• number of side electrodes;
• use resource;
• self-cleaning ability.

There is a variety that has become very popular - iridium candles. Theoretically, their design has a thinner diameter of the central wire, unlike others, it conducts current better and generates a more powerful spark, which greatly simplifies engine operation. There are many myths that iridium products significantly increase the performance and power of car engines, in practice, the increase in efficiency is not large. Consider the best types of heating systems in a little more detail:

• Heaters perform the same function in diesel engines as the ignition system in gasoline engines. They are called "preheat plugs". They are responsible for facilitating cold starts, which is especially important for diesel engines, which are increasingly found on our roads. The heater is a resistor designed to increase the temperature inside the combustion chamber. Its shape resembles a ballpoint pen, in which one end is heated before the start. It is important to remember that it is desirable to replace all elements at the same time so that the work is rhythmic.
• Candles are the elements that ignite the mixture of gasoline and air inside the combustion chamber. The spark is generated due to the difference in electrical potential. In the case of normal motor operation, this process is repeated an average of 2000 times per minute.

If the ignition system is replaced in time, premature wear of other parts of the vehicle can be avoided. If you find the following signs, it's time to consider buying new devices:

• loss of power while driving;
• increased fuel consumption, becausecombustion of gasoline occurs incorrectly due to a spark generated at the wrong time;
• difficulty starting, especially in cold weather, knocking when the engine is running;
• dark smoke from the exhaust.

Consider the process of attaching a new incandescent system, we will provide step-by-step instructions and tips for installing the product with your own hands at home.

How to choose the right spark plug

It is important for a car to purchase high-quality spare parts, in order to buy a good product, you need to pay attention to the following selection criteria:

1. It is necessary to order a product compatible with the car engine. Most of the top brands clearly indicate the vehicle models that their product will be compatible with. Therefore, you need to carefully study the manufacturer's compliance list.

2. In addition to compatibility, you must choose the type of construction, since various options are available. The most common:

• Cupro-Nickel: The name may confuse you because the majority of these items are made of nickel, with only the inner core being made of copper. It conducts current well, which is why most electrodes are made from it. The product is inexpensive, its disadvantage is that it has a short service life, even if used in a high energy ignition system without a distributor. For many vehicles, this option will come in handy, it will suit natural gas engines.
• The next type has a platinum center pin. It is expensive due to the rarity of this element, it is harder than nickel, so you can be sure that the product will not corrode. Platinum will not allow the gap at the tip to expand, wear out, which directly affects the efficiency of the engine.There are models with one or more electrodes. This helps to generate the spark in the best possible way. In terms of service life, it's double that of the standard nickel/copper construction.
• Iridium Device: If you want flawless, smooth engine performance, there is nothing better than Iridium. It has a longer service life than traditional models. Thin wire center contacts are designed to conduct current most efficiently. These are expensive products, but the price is offset by incredible performance.
• Silver candles are the option with the best thermal conductivity. The problem with this product is its durability. The precious metal cannot be compared in terms of wear resistance with platinum or iridium models.

All designs fit any vehicle in one way or another, but the platinum-based option is more versatile. It is relatively affordable than iridium and much better in performance and durability than copper-nickel devices.

3. It is important to decide: "What kind of ignition is needed, cold or hot?" If we give a very simple, but accurate definition, we can say that candles that are heated during operation are hot. And those that do not reach high temperatures are cold.

The metal shell of the structure operates at the same heat as the head. The elements are screwed together, forming a chamber in which heat is distributed evenly.
Hot models have a long insulator tip with a large surface area, causing all parts to become hot. At the same time, cold ones have a small cap that helps to quickly remove excess degrees from the combustion zone.

Russian-made models usually have a numerical heating rating. Their scoring isn't always consistent because some brands give higher numbers while others underestimate.

It becomes extremely difficult for customers to choose the right product with such a variety of options. It is best to order a design in accordance with the car engine and year of manufacture.

4. If you do not want to suffer for a long time during replacement, it is better to choose a design that is easy to install.
By applying the above selection criteria, a performance model can be easily determined.

Below is a compatibility table for candles on a Lada car:

How to replace candles

Before installing the novelty and removing failed spare parts, it is necessary to disconnect the negative pole of the battery, which, unlike the positive one, has a black color and a “-” symbol. The price of replacing the device is very low, ranging from 150 rubles for each. The cost will increase or decrease depending on the volume, number of cylinders.

On average, gasoline vehicles are serviced every 60,000 km. However, depending on how heavily the machine 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 candle is faulty, it is advisable to replace all at once. Below we provide step-by-step instructions necessary for the installation of equipment:

• a wrench of a certain width so that you can unscrew and secure a new device;
• ratchet or hexagonal head facilitating the removal of the product;
• compressed air compressor to thoroughly clean all openings and connections;
• goggles to protect the eyes from debris that can bounce off while blowing;
• you need to wear 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 work after 2 hours from the moment the equipment is used. 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 by gently pulling upwards to avoid damaging it. Do this carefully, remembering the location of all the wires, so that you can then secure everything in its place.

3. Remove the plug and spool using a hex key, 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 contaminants. It is important to wear protective goggles.

5. Attach the new product. Lubricate it and start screwing it in gently by hand with a little bit of force, then use a wrench to tighten the device, being careful not to overdo it too much.

6. Insert the ignition coil by 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 coil itself.

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

If you've done everything right, using the correct wrench size, by unscrewing the heads, the car will start and run more efficiently.
