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

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