  • Product Information

    These high-performance spark plugs operate based on the state-of-the-art surface air-gap principle. It is the first spark plug with four thin ground electrodes and a sharpened, silver-plated central electrode.

    This technological superiority is also evident in the engine's performance, in all driving situations, over the entire life of the spark plug.
