Bosch Platinum+2 Spark Plug #4308

If you're looking for the maximum performance from your car, the Bosch Platinum+2 Spark Plug #4308 is an ideal choice. Unlike conventional air-gap spark plugs, they use innovative surface air-gap technology. The spark of these Bosch spark plugs travels over the surface of the insulator nose and then arcs across the air gap to a multiple ground electrode for a longer spark. The center electrode tip helps reach a self-cleaning temperature only seconds after starting. This increases wear resistance without increasing the voltage requirement. Plus, the yttrium alloy ground electrodes in these auto spark plugs help to reduce gap wear and oxidation, extending the service life of the spark plug. They're pre-gapped, making installation faster. They also generate 15 ft lbs of torque for smoother acceleration, giving you a better ride. These quality parts also improve gas mileage through improved efficiency, saving you money.
