NGK spark plugs are designed for a long service life and maximum performance.

Each NGK plug features high alumina ceramics for better heat transfer and electrical insulation. Patented triple gasket sealing process eliminates the possibility of combustion gas leakage. The solid copper core increases heat and spark transfer while the longer insulator nose prevents fouling and misfiring.

Key Features

  • They are resistant to carbon buildup and pre-ignition
  • Longer insulator nose prevents fouling and misfiring
  • Solid copper core aids in heat removal
  • Alumina ceramics for better heat transfer
  • Triple seals prevent leakage
  • Corrugated ribs prevent flashover

Plug Selection

To ensure optimum performance please consult your owner's manual to determine the correct spark plug for your engine.

With a triple-gasket sealing process that keeps them secure at 50 G's, these plugs can withstand the roughest ride. There is also a solid copper core for greater spark and heat transfer, longer insulating nose to prevent fouling even when idling and a double-dipped zinc-chromate shell to resist corrosion and rusting.
