Good candles for cars are those made of platinum and iridium, but the price is very high. You can buy ordinary multi-electrode plugs, which are practically no different from their "precious" counterparts.
I must say that every motorist has his own opinion on this matter, and those candles that one calls the best, the other can criticize to smithereens. However, there is a certain kind of candle that most motorists like.
How to choose
First of all, when choosing candles, drivers pay attention to their size and parameters of the cal number, although some are not particularly familiar with the latter. This feature is mainly attracted by fans of fast driving, because the higher the calorie number, the higher the temperatures the candle can work with. But in order not to make a mistake and not to repair the engine in the future, candles should always be purchased in strict accordance with the instructions for the car.
The next parameter is the design of candles, in which both one and several electrodes can be used. Single-electrode spark plugs are short-lived and cannot reveal all the capabilities of the engine, although they have a rather low price. Multi-electrode spark plugs improve spark formation, allow the engine to develop more power, providing better fuel combustion in the cylinders and increasing the environmental parameters of its operation. Many manufacturers produce both single-electrode and multi-electrode plugs, which allows the buyer to make a choice in favor of saving money or in favor of stable and better motor operation.
Precious metal candles
Today, platinum and iridium candles have appeared on the market, the service life of which has increased significantly. In addition, they are equipped with a self-cleaning system, increase the reliability of the engine, improve dynamics and reduce harmful emissions, and also save fuel, allowing you to recoup your own purchase costs in 3.5 months. The idea of such a development of manufacturers was prompted by athletes who sharpened the central electrode "on a cone" in order to increase the power of the motor. True, after such treatment, the candles did not "live" for a long time. The engineers proposed to make a thin central electrode from a metal capable of resisting destruction and thus solved this problem.
Therefore, motorists who want to buy good candles can be advised to take with iridium and platinum electrodes, for example, Denso Iridium Power, Bosch Platinum, Beru Ultra-X Platinum and others. If this is not possible, then you should limit yourself to ordinary multi-electrode plugs, but only from well-known manufacturers - Bosch W7DTC, Brisk DR15TC1, Ultra-X and others. In no case should you take candles from your hands, only trusted service centers and shops deserve trust.
