Best spark plugs in 2024

Car candles are not the goods that are primarily interested in the owner of the car, but when problems with ignition arise, interest immediately appears, and a lot of questions on the topic "Which company is better" or "What should be the selection criteria."

Studying the popularity of the models and their functionality, you come to the conclusion that a wide range of spark plugs is produced by manufacturers that are not related to well-known automotive companies. This has an undeniable advantage, since the logo of a promoted brand on any auto part increases its cost by a quarter. From this it follows that it is better to buy consumables from the manufacturer, thereby avoiding a significant mark-up from the automaker.

How to choose the right spark plugs?

Which spark plugs to choose?

Various types of candles are provided on the modern market. They are differentiated according to various criteria, for example, use in gasoline or diesel engines. There are also differences associated with the number of electrodes (two and multi-electrode) and the material (iridium, platinum) from which they are made.

The most popular models belong to brands such as:

• NGK. The brand successfully cooperates with such business sharks as Ferrari, BMW, Volvo, etc.
• Bosch. Provides parts for Mitsubishi, Toyota, Audi, Fiat.
• Brisk. Creates consumables for BMW, Skjoda, Opel and Audi.
• Champion. Has a contract for the creation of car products for Alfa Romeo, Suzuki, Jaguar and other brands.
• Denso. A famous Japanese corporation that creates quality parts for various cars.

Purchasing spark plugs from these firms will be a great savings and an excellent alternative for any brand of your vehicle. The quality of the products is excellent and appreciated by many professionals.

Visually about spark plugs:

Most popular designs

Conventional spark plugs. They are classic single-electrode devices: a white ceramic body on top and a threaded metal bottom. Such models attract attention with their budgetary price, simplicity and the ability to improve engine performance. But, of course, there are some drawbacks. These include the minimum resource.

Multi-electrode plugs. The peculiarity of such devices is that several additional, so-called lateral ones are located around the central electrode. There can be 3 or 4. The result is a kind of flower. The advantages of this kind of devices are that you can make a choice from which electrode to receive a spark. And, accordingly, the service life is increased. Also, the ignition of the torch passes through the center of sparking and there are no breaks in it, which favorably affects the increase in engine power.

Candles with platinum and iridium. A significant drawback of these devices immediately catches the eye, since this is a "biting" price tag. You might think that it is unreasonably overstated, but in reality it is not so.Thin electrodes have an unpleasant property to wear out quickly, and when they are made of metal, they resist destruction. In addition, such spare parts have a number of other advantages: self-cleaning, the ability for additional insulation, an increased number of electrodes, and other nuances. This is definitely worth paying extra for.

The best spark plugs.

77 00 500 168

Renauilt spark plugs with marking 77 00 500 168 have proven themselves to be excellent. The technical characteristics of this spare part are excellent for the K7M engine. The plant constantly carries out strict quality control, which guarantees flawless work.

The French manufacturer Eyiem is the main supplier of these devices to a large part of European factories.

Thanks to two side electrodes, the life of the candles is increased. And the central electrode, flying out into the combustion chamber, competently ensures the ignition of the mixture.

Numerous tests carried out have revealed that 77 00 500 168 are a quality product, with a decent resource, but without record indicators. The cost is about 200 rubles.

• The quality is at the highest level;
• Complies with the declared working conditions.

• Prices often vary.

Denso K20XTR

The manufacturer is Japan, which cannot but please motorists, since such products are an unsurpassed copy of unique spare parts and only the marking can give out where the candles are actually created. The surface of the electrodes is nickel, which has a beneficial effect on the resistance to erosion. The long service life of the product and stable sparking ensures quiet operation of the engine and ensures that the fuel consumption is regular. The average price for a car product varies around 250 rubles.

• Excellent quality;
• Erosion resistant electrodes.

• Price.

Beru Z193

This is a kind of classic of the genre and is popular with buyers. Candles confidently serve their life from one TO to another, do not let the owner down, but at the same time they do not amaze with excellent results. The thread length is 19 mm and the tightening torque is 25 Nm. The design is single-electrode, due to which the service life is noticeably reduced. The average cost is only 140 rubles.

• The price is available to every car owner;
• Counterfeiting on the market is minimal.

• The minimum spark gap reduces the power of the spark produced;
• The ventilation of the spark gap is reduced due to the operation of the central electrode, which is "recessed".

Bosch FR7LDC Plus (0 242 235 668)

An excellent alternative to classic spark plugs, and all because Bosh FR7LDC + (0 242 235 668) is a two-electrode spare part. The quality of the product is high and can be compared with many leaders in this range. Yttrium is added to the material of the central electrode, which guarantees resistance to spark erosion, and therefore raises the resource of the product to a higher level.

The main characteristics of the Bosh FR7LDC + (0 242 235 668) are similar to those from Beru. The price fluctuates around 160 rubles.

• Decent resource;
• The parameters are the same as most standard candles.

• Often counterfeited.

NGK BKR6EK (2288)

Spare parts from a Japanese manufacturer have stable sparking, have excellent resistance to the appearance of chemical deposits and are famous for high-quality work at high voltage. But the main thing is that the candles are original, and not a Chinese fake, otherwise disappointment will be inevitable. The device has a long service life. The average price is about 210 rubles.

• No problem with purchase, sold in many retail outlets.

• The number of fakes is high;
• Rough stamping is observed at the side electrodes.

Denso PK20PR-P8

The Japanese manufacturer creates its product from platinum, which gives it a place of honor in the ranking of quality goods. Another attraction for buyers is the optimal price.The performance characteristics are excellent: thanks to the platinum coating, a high resource and excellent quality are provided.

In conditions where there are increased loads, Denso PK20PR-P8 guarantees continuous operation of the ignition system. The model has an impeccable surface treatment of the case, and the contact output pleases with its perfect matte surface.

• High quality;
• Long resource.

• Dimensions of the interelectrode gap.

NGK BKR6EIX (6418)

Model NGK BKR6EIX (6418) has an iridium electrode. The device is characterized by the highest and most stable sparking. It also has good resistance to chemical deposits that can occur during operation. Provides high-quality functionality at increased voltage.

NGK is famous not only for supplying the finest factory quality products, but also for the fact that its services are used in the legendary Formula 1 when equipping cars with spare parts.

The resource of iridium candles is at the proper level and they can give a passage of up to 50,000 km. The price of NGK BKR6EIX (6418) is quite high and reaches 530 rubles.

• Stability in sparking;
• An incredibly long service life;
• A car equipped with such candles just flies.

• Not everyone can afford the price.

Brisk Premium LOR15LGS

The Brisk Premium LOR15LGS model pleases motorists with brilliant performance and a design that is not quite typical. The shape of the side electrodes of this device is unusual, but the fact is that they "look down", that is, they are lowered along the rod. Because of this, the sparks produced "surround" the main electrode along the entire length of the exposed portion. Due to this, the fuel-air mixture is ignited at the initial stage of feeding into the combustion chamber. This action saves fuel well, which is a definite plus for any driver. The price is about 700 rubles.

• Non-standard shape of electrodes;
• Dense spark;
• Fuel economy;
• Long service life.

• "Biting" cost.

Beru Ultra-X 49

Beru Ultra-X 49 is produced by a German company. The difference between these candles and others is that the side electrodes are asymmetrically located: two of them separate 0.8 ml from the rod, and the rest are at a distance of 1.2 ml. This provides competent spark support, regardless of operating conditions.

An additional advantage is that Beru Ultra-X 49 is compatible with gas sources.
It costs about 600 rubles.

• Operates on liquefied natural gas;
• Fuel efficiency at altitude;
• Even if there is a lot of pollution, the spark is stable;
• Remarkable price-to-quality ratio.

• The percentage of power increase, in the case of an open damper, is low.

Bosch WR7DP

The German manufacturer has created a unique device of its kind, since the core of the central electrode with a ceramic insulator emits an original spark in the form of a small flame discharge. The created discharge has amazing stability, regardless of the voltage in the machine's network.

If the car is fueled with high-quality fuel, then the resource of one Bosch WR7DP reaches 55-60 thousand kilometers. Platinum sputtering plays an important role in this. But it is worth considering such a factor as roads. And they sometimes have a sad effect on spare parts, forcing them to use up the resource faster.

Average cost - 250 rubles

• State-of-the-art central electrode design;
• The optimal ratio of quality and price;
• Arc spark in the form of a plasma form;
• Stability of work is provided at any voltage;
• Modifications are suitable for cars such as Chevrolet, Renault, VAZ, etc.

• A little more fuel is consumed than with ordinary standard candles.

So what should you choose?

When the old candles completely use up their resource, you can make the mistake of purchasing the first spare parts on the market as a replacement.This decision will be fundamentally wrong, since it is worth focusing on parameters such as size and heat rating.

As for the size, if it turns out to be too small, then there will be problems with screwing in the device. The electrodes simply will not be able to reach the combustion chamber. If the size is large, then a new problem will appear, since the candles will "crawl" out of place. In addition, the piston will hit the electrodes, and this is fraught with engine breakdown.

Now let's go over the incandescent number. What it is? This is the name of the value that tells us the time after which the device will reach the state of glow ignition. That is, the glow number is a kind of indicator of the heat performance of the candle. If the number reaches high values, then the candle becomes colder, which means it may well function with high temperatures. And if the number is low, then at the exit we have a hot candle, which quickly overheats.

Therefore, before purchasing candles, you should read the instructions for the car, because analogs are indicated there.
