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

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