The Bosch Platinum+2 spark plug offers a revolutionary firing technology, which combines the advantages of platinum, multiple electrodes and surface air gap technology for optimum engine performance. Unlike conventional air gap spark plugs, the Platinum+2 uses surface air gap technology. The spark of a Platinum+2 first travels over the surface of the insulator nose and then arcs across the air gap to a ground electrode for a longer spark, without increasing the voltage requirement. Plus, the yttrium alloy ground electrodes help to reduce gap wear and oxidation, extending the service life of the spark plug.
