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.

- Highly resistant to material erosion
- Improved spark plug efficiency
- Nickel-plated rolled threads is used for complete anti-seize and corrosion protection
- Ribbed insulator design prevents misfires due to flash-over
- The center electrode tip is made from a silver alloy, ensuring long service life and ignition sparks with increased energy
Application Summary: BMW, 1989-1980
