Features & Benefits:
  • LIFESPAN / DURABILITY
    • Platinum Center Electrode -- offers superior resistance to erosion and corrosion compared to conventional Copper / Nickel plugs, for consistent performance.
    • Titanium-Enhanced Ground Electrode -- increases durability and minimizes tip 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.
  • EFFICIENCY / FUEL ECONOMY
    • Twin Tip -- Superior ignitability from the twin tips means more efficient combustion, which yields better engine performance in terms of power and fuel economy. Better mileage, more power, and faster starts, all while reducing carbon emissions are what places the Platinum TT heads above the competition.
