OE Fine Wire Double Platinum
Bosch Double Platinum spark plugs are engineered to extend performance life and durability. The fine wire design of the center electrode improves ignitability and performance in your engine while the platinum tip on both the center and ground electrodes ensure longer life.

Center Electrode

  • 360° continuous laser welding to fuse the platinum firing pin promotes durability and longer life
  • Fine wire design delivers better ignitability and performance
  • Copper core provides broader heat range to resist pre-ignition and fouling

Ground Electrode

  • Laser welded platinum inlay promotes durability and longer life
  • Copper core (when required) provides broader heat range to resist pre-ignition

Nickel-plated shell with rolled threads

  • Provides complete anti-seize and corrosion protection

Ribbed insulator design

  • Prevents misfires due to flash-over


  • No need to gap for faster installation
