Features & Benefits:
  • LIFESPAN / DURABILITY
    • Platinum Center Electrode -- offers superior resistance to erosion and corrosion compared to conventional Copper / Nickel plugs, for consistent performance.
    • Platinum Ground Electrode -- extends the life of the plug by resisting gap erosion.
    • Patented 360-Degree Laser Welding -- creates the highest quality bond for structural support of the center electrode
  • PERFORMANCE / IGNITABILITY
    • 1.1mm Platinum Tip -- results in less obstruction of the spark growth, which means better ignitability for a more powerful combustion.
