    Top performance: Noble metal for winners

    Platinum is the most precious of all the noble metals. And it is also the most valuable for Bosch spark plugs, as it offers the lowest thermal and electrical conductivity of any of the noble 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 noble metal electrodes. Double platinum spark plugs are provided with laser-welded platinum tips (center electrode) or the electrode is platinum-tipped (ground electrode).

    Even more advantages are the result:

    • Rapid attainment of operating temperature
    • Increased cold starting reliability
    • Protection of engine and catalytic converter
    • Set electrode gap
    • Fine platinum-iridium electrodes for enhanced ignition and smooth engine operation
    • Ideal for use in gas-driven vehicles
