Bosch Platinum+2 Spark Plug #4303

Get smoother acceleration, better gas mileage and optimum engine performance with the Bosch Platinum+2 Spark Plug #4303. Unlike conventional air gap spark plugs, the Platinum+2 uses surface air gap technology. The spark of a Bosch spark plug 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 to keep it operating longer. The platinum center tip helps the Platinum+2 reach a self-cleaning temperature after starting and provides excellent wear resistance. These convenient auto spark plugs can be a good replacement unit when doing home engine repairs or tune ups.
