In order for the fuel-air mixture of the engine to ignite perfectly, a stable spark is required at the right moment. Therefore, the correct spark plug selection is essential for optimal combustion and power development of the engine. Particular attention should be paid to the heat value as specified by the manufacturer. Since each manufacturer specifies the heat value differently, a Bosch heat value of 3, for example, may correspond to an NGK value of 9. For reference, each vehicle manual lists the manufacturer's specifications along with alternative spark plugs and their exact designations or type codes.

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

Caution is required when using suppressed spark plug connectors; double suppression does not equal better, in this case, no suppressed spark plug should be used, as the overall suppression resistance would be too high.
