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

Spark plugs are found in any gasoline engine, since they generate the necessary spark that ignites the mixture of air and gasoline, 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, pressure, vibration, products quickly wear out, especially contacts, which are key elements of the device. The more powerful and faster the spark generated, the more efficient the start, minimizing wear on other components of the electrical network and battery.

In our review, we will provide recommendations: what to look for so as not to make a mistake when choosing a product, which brand model is best to buy. We will get acquainted with popular manufacturers, descriptions of ignition systems for Lada Granta, Priora and Kalina, and guide you on the average price.

Types of candles, their structure

Not enough horsepower during acceleration, slow start, fuel consumption is growing at a gigantic rate, is the car shaking? You need to take a closer 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 spark plugs changes. Let's consider the components of the system design and their functionality:

• top terminal: ignition coil connection point;
• main body: high voltage generation and heat insulator;
• thread: screwing a product into the cylinder head;
• electrode: spark source, 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 engine starting assistance. We list several main characteristics of the system:

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

There is a variety that has become very popular - iridium spark plugs. Theoretically, their design has a thinner central wire diameter than 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. Let's look at the best types of glow 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, one end of which is heated before starting. It is important to remember that it is advisable to replace all elements at the same time so that the work is rhythmic.
• Plugs are elements that ignite a mixture of gasoline and air inside the combustion chamber. A spark is generated due to a difference in electrical potential. If the motor is operating normally, this process is repeated an average of 2000 times per minute.

If you replace the ignition system in time, you can avoid premature wear of other parts of the vehicle. If you notice any of the following signs, it's time to consider purchasing new devices:

• loss of power while driving;
• increased fuel consumption, because gasoline combustion 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 on the exhaust.

Let's look at the process of attaching a new heating system, provide step-by-step instructions and tips for installing the product yourself at home.

Noble metals: practical meaning of application

As we already said in the last paragraph, the transition to a multi-electrode circuit did not bring much practical benefit in increasing the service life of spark plugs. In fact, the fight against the very cause of natural wear of spark plugs, that is, erosion of contacts, was replaced with a palliative - the substitution of “spare” ones. To increase the immediate reliability of the electrodes, the design of the spark plugs was significantly redesigned.

In “platinum” and “iridium” spark plugs, the main feature that catches the eye is a very thin central electrode, which precisely localizes the point of origin of the spark - opposite it, a plaque of the corresponding metal is soldered on the side electrode, and the central electrode is also covered with it.

The advantages of such candles are obvious: the electrodes have a service life that, under normal conditions, is two to three times longer than that of conventional candles. The thin central electrode is perfectly self-cleaning, which also contributes to reliable operation.

The disadvantages, alas, are also significant. The first is the price: a set with the Platinum or Iridium inscription will cost at least two to three times more than regular candles. The second, oddly enough, is tenderness: non-fading carbon deposits instantly kill such candles, and mechanical cleaning is contraindicated for them, just like the old-fashioned burning with a torch. First of all, we are, of course, talking about the notorious ferrocene, which is still not uncommon to encounter.

How to choose the right spark plug

It is important to purchase high-quality spare parts for a car; 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 machine's engine. Most of the best brands clearly indicate the vehicle models their product will be compatible with. Therefore, you need to carefully review the manufacturer's compliance list.

2. Apart from compatibility, you need to choose the design type as there are various options available. The most common:

• Copper-Nickel: The name may confuse you because these products are primarily 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. Many vehicles will benefit from this option; it is suitable for natural gas engines.
• The next type has a platinum center contact. It is expensive due to the rarity of this element, which is harder than nickel, so you can be sure that the product will not corrode. The platinum will prevent the tip gap from widening and wearing out, which directly affects the efficiency of the engine. There are models with one or more electrodes. This helps generate the spark in the best possible way. In terms of service life, it is twice that of standard nickel/copper construction.
• Iridium Product: If you want flawless, smooth motor performance, there is nothing better than an Iridium product. It has a longer service life than traditional models. The thin wire central contacts are designed to conduct current most efficiently. These are expensive products, but the price is offset by incredible performance.
• Silver candles are an option with the best thermal conductivity. The problem with this product is its durability. The precious metal cannot match the durability of platinum or iridium models.

All designs fit any vehicle in one way or another, but the platinum-based option is more universal. 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?” To give a very simple but precise definition, we can say that candles that glow 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 to each other, 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 quickly remove excess degrees from the combustion zone.

Russian-made models usually have a numerical heat rating. Their assessment is not always consistent because some brands give higher values ​​while others underestimate.

It becomes extremely difficult for buyers to choose the right product with so many options. It is best to order the design in accordance with the car's 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 productive model can be easily determined.

Below is a table of compatibility of spark plugs for a Lada car:

Non-traditional schemes

Some of the design solutions in spark plugs of an unconventional design can be called conditionally working - by improving one thing, they worsen another. The simplest example is the NGK V-Line series of spark plugs: their central electrode has a groove, so the spark always jumps between the edge of the electrode and the side one. In theory, this improves ignition of the mixture by moving the spark into a better ventilated space and stabilizing the spark point, but the erosion of such a central electrode is accelerated.

Some of the candles on the market cannot be classified as anything other than “Herbalife” from the car market: all sorts of “pre-chamber”, “torch” and so on candles, at best, work no better than standard ones, at worst, they quickly deteriorate. For example, in the notorious “Bugaets” candles, the soldered skirt not only worsened the ventilation of the spark gap, but also burned out, and sometimes went into “free flight” into the combustion chamber. Of the designs that are workable, but useless in the practice of an ordinary motorist, we note only spark plugs that do not have a side electrode at all - they were originally created to work in ultra-high boost engines in order to avoid overheating of the protruding side electrodes; in a normal city cycle on a “civilian” boost level motor, they They clean themselves disgustingly and guarantee rough idling even on ideal quality gasoline.

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.

Troubleshooting

Fortunately, a performance check is available to every car enthusiast and does not depend on technical equipment or the availability of expensive diagnostic equipment. There are several simple, common ways to conduct an independent test: 1. Analysis of the presence and quality of the spark. 2. Testing using a multimeter.

In order to use the first method, it is necessary to dismantle and clean the working surface of the spark plug. Next, a high-voltage wire is connected to the spark plug, the housing is brought to the power unit and the starter is started briefly (for a few seconds). Normal operating parameters are the production of a clear, blue spark. Evidence of a malfunction is a yellowish, reddish color of the spark or its complete absence. The second way is as follows. We take a multimeter and switch the measuring mode of the device to 20 kOhm. We attach the red probe to the side electrode, and connect the black one directly to the contact (where the high-voltage wire is put on). We measure the resistance readings on all four products. Normal resistance levels range from 2 to 4 kOhms. If the indications are different, normal operation of the internal combustion engine is not guaranteed.
