Features & Benefits:
  • LIFESPAN / DURABILITY | Iridium alloy is 6X harder and 8X stronger than Platinum
    • Iridium with Rhodium Center Electrode -- has the highest concentration of Iridium of any spark plug and outperforms in the most severe engine temperatures, resisting oxidation and voltage wear for over 100,000 miles.
    • Patented 360-Degree Laser Welding -- creates the highest quality bond for structural support of the center electrode.
  • PERFORMANCE / IGNITABILITY
    • 0.4 mm Fine Wire Iridium Center Electrode -- achieves higher ignitability and requires lower spark voltage to enable high-response driving with fewer misfires. As a result, acceleration improves in comparison with normal plugs.
    • Tapered Cut Ground Electrode -- improves firing performance by reducing quenching.
  • EFFICIENCY / FUEL ECONOMY
    • Patented U-Groove Ground Electrode -- enables complete combustion by allowing the spark to fill the gap created by the U shape. The ball of fire created in the U-Groove develops a larger and hotter flash front that virtually eliminates excessive fouling and erratic starts caused by poor fuel mixtures.
