In order for the gasoline-air mixture of the engine to ignite perfectly, a stable spark is needed at the right moment. Therefore, the correct selection of spark plugs is essential for optimal combustion and performance development of the engine. Special attention should be paid to the heat value according to the manufacturer's specifications. Since each manufacturer defines the heat value differently, for example, a Bosch heat value of 3 may correspond to an NGK value of 9. For reference, in every vehicle manual, the manufacturer's specifications along with alternative spark plugs and their exact designations or type codes are listed.

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