Bosch Platinum2 Spark Plug

More pure platinum with two ground electrodes and a more powerful spark. 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 uses 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.   Only Bosch offers this revolutionary firing technology, which combines the advantages of multiple electrodes, pure platinum and surface air gap technology for optimum engine performance.   Features Benefits Revolutionary firing technology featuring multiple spark paths Delivers a longer and more powerful spark for optimum engine performance More pure platinum vs. Bosch Platinum For smoother acceleration, better mileage and optimum engine power Two ground electrodes Provides optimal access to the air/fuel mixture for more efficient combustion, plus a longer performance life Electrode gap is factory set Provides ease of installation - never requires adjustment
