In order for the gasoline-air mixture of the engine to ignite perfectly, a stable spark is needed at the right time. Therefore, the correct choice of spark plug is essential for optimal combustion and performance development of the engine. Special attention should be paid to the heat range as specified by the manufacturer. Since each manufacturer displays the heat range differently, for example, a Bosch heat range 3 can correspond to an NGK value of 9. For orientation, vehicle manuals list the manufacturer specifications along with alternative spark plugs and their exact designations or type codes.

We work with official vehicle usage lists from manufacturers and offer you exactly the right spark plug for your vehicle.

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