NGK spark plugs are installed worldwide in all vehicle categories. From the original engine to racing, NGK is one of the top manufacturers of spark plugs. And it is important to install a high-quality and above all suitable spark plug, as the cost of engine damage is in no relation to the price of a good spark plug. The right heat value is the most important thing when choosing the spark plug. A candle that is too hot may result in engine damage and too cold can lead to constant soot of the candle. Therefore, it is important to always use the same heat value as that of the original candle for unturned engines. For sports and racing engines, it is advisable to use a slightly colder candle.
