In order for the fuel-air mixture in the engine to ignite perfectly, a stable ignition spark is required at the right time. Therefore, the correct choice of spark plug is essential for optimal combustion and performance development of the engine. Particular attention should be paid to the heat rating specified by the manufacturer. As each manufacturer indicates the heat rating differently, a Bosch heat rating of 3, for example, can correspond to an NGK value of 9. For orientation, each vehicle manual lists the manufacturer's specifications with alternative sparking plugs and their exact designations or type codes.

Care should be taken when using suppressed spark plug connectors; double does not mean better, in this case, a suppressed spark plug should not be used, as the overall suppression resistance would be too high.
