In order for the fuel-air mixture of the engine to ignite perfectly, a stable spark is needed at the right moment. 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 value according to the manufacturer's specifications. Since each manufacturer indicates the heat value differently, for example, a Bosch heat value of 3 can correspond to an NGK value of 9. For guidance, the manufacturer's information on alternative spark plugs and their exact designations or type codes can be found in every vehicle manual.

Care should be taken when using suppressed spark plug connectors; doubling is not always better. In this case, a suppressed spark plug should not be used, as the overall suppression resistance would be too high.
