If you require smoother acceleration, better mileage, and optimum engine power, Platinum2 is the spark plug for you. Unlike conventional air-gap spark plugs, Platinum2 spark plugs use surface air-gap technology. The spark of a Platinum2 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. Bosch spark plugs use revolutionary firing technology, which combines the advantages of multiple electrodes, pure platinum, and surface air-gap technology for optimum engine performance.
