Bosch Platinum Spark Plugs

  • Product information

    Top performance using precious metals

    Platinum is a precious metal and it is also the most valuable metal for Bosch spark plugs. It offers the lowest thermal and electrical conductivity of any of the precious metals as well as the least thermal expansion. Due to the fact that it is largely resistant to corrosion, Bosch platinum spark plugs also have a particularly long service life. Our platinum iridium spark plugs feature a copper core and precious metal electrodes. Double platinum spark plugs are provided with laser-welded platinum tips (center electrode) or the electrode is platinum-tipped (ground electrode).
