NGK Spark Plugs are designed to operate over a much wider heat range than ordinary plugs. They resist carbon buildup and pre-ignition. Each features high alumina ceramics for better heat transfer and electrical insulation. A patented triple gasket sealing process eliminates the possibility of combustion gas leakage, and a longer insulator nose prevents fouling and misfiring. A solid copper core and its nickel tipped electrode provide a longer plus life.

  • Tapered-cut ground electrode improves ignitability and reduces quenching
  • 98% pure copper core increases heat dissipation for more reliable starts and prevents spark plug from overheating
  • High-grade alumina silicate ceramic insulator for superior strength and heat transfer
  • Iridium is six times more durable than platinum
  • Quantity: 1 per package
