Backed by a 4 year satisfaction guarantee.
Bosch Platinum Spark Plugs are engineered for up to 2X longer service life.*
Bosch copper core spark plugs feature a heavy-duty nickel center electrode for longer lasting service life compared to standard copper plugs.
Bosch Silver Spark Plugs are engineered for older European performance cars, as well as some motorcycle applications. These types of vehicle engines operate at particularly high combustion chamber temperatures, increasing the wear on the electrodes. Bosch uses silver alloys in the center electrode tip to resist wear and improve spark plug efficiency.
Bosch Platinum+4 Spark Plugs deliver smoother acceleration, top fuel economy and ultimate engine performance. Bosch Platinum+4 Spark Plugs reach self-cleaning temperatures faster for quicker starts, smoother acceleration and increased fuel efficiency.
