    Innovative and powerful: High-end for optimum starting

    This high-performance spark plug operates on the latest surface air gap principle. It is the first spark plug to have four thin ground electrodes with a pointed, silver-plated center electrode. This technical superiority also becomes apparent in the engine performance in all driving situations and throughout the entire service life.

    The advantages at a glance:

    • Appreciably better acceleration
    • Far smoother operation
    • Superior engine elasticity
    • Factory-set electrode gap
    • Eight possible spark gaps for greater ignition reliability
    • Self-cleaning thanks to surface gap design
    • Extended heat range: Capacity for up to three times more cold starts than with conventional spark plugs
    • Enhanced environmental and catalytic converter protection

    And: The spark plug can also be used in older vehicles, so that they too can benefit from the advantages of modern spark plug technology.
