Copper with Nickel Spark Plugs

Bosch copper core spark plugs feature a heavy-duty nickel center electrode for longer lasting service life compared to standard copper plugs.

Silver Spark 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.
