In order for the gasoline-air mixture of the engine to ignite perfectly, a stable ignition spark is required at the right moment. The correct spark plug choice is therefore essential for optimal combustion and performance development of the engine. Special attention should be paid to the thermal value according to the manufacturer's specification. Since each manufacturer lists the thermal value differently, for example, a Bosch thermal value of 3 can correspond to an NGK value of 9. For reference, each vehicle manual contains the manufacturer's specifications with alternatively applicable spark plugs and their exact designations or type codes.

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