Best spark plugs in 2020

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.

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.
