For the gasoline-air mixture of the engine to ignite perfectly, a stable spark must occur at the right time. Therefore, the correct spark plug choice is essential for optimal combustion and performance development of the engine. Special attention should be paid to the heat value as specified by the manufacturer. Since each manufacturer states the heat value differently, a Bosch heat value 3 can correspond, for example, to an NGK value of 9. For orientation, each vehicle manual lists the manufacturer's specifications with alternatively usable spark plugs and their exact designations or type codes.

We work with official vehicle application lists from the manufacturers and offer you exactly the right spark plug for your vehicle.

Caution is advised when using suppressed spark plug connectors; double is not necessarily better, in this case, a suppressed spark plug should not be used, as the total suppression resistance would be too high.
