In order for the fuel-air mixture of the engine to ignite perfectly, a stable ignition spark is required at the right moment. Therefore, the correct spark plug choice is essential for optimal combustion and performance development of the engine. Special attention should be paid to the thermal value according to the manufacturer’s specifications. Since each manufacturer indicates the thermal value differently, for example, a Bosch thermal value of 3 corresponds to an NGK value of 9. For reference, the manufacturer’s specifications with alternative spark plugs and their precise designations or type codes are listed in each vehicle manual.

Care should be taken when using shielded spark plug connectors; double is not always better, and in this case, a shielded spark plug should not be used as the overall shielding resistance would be too high.
