Features & Benefits:
  • PERFORMANCE / IGNITABILITY
    • Nickel Alloy Center Electrode -- for reliable, cost-effective performance.
  • EFFICIENCY / FUEL ECONOMY
    • Patented U-Groove① 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.
