NGK 5509 spark plug for the 1992-1998 Porsche 911 H6 3.6L and other vehicles ignites the air-fuel mixture in the cylinder. It suits vehicles with nickel alloy plugs and is not recommended on vehicles with factory precious metal plugs.

  • Trivalent metal plating for anti-corrosion and anti-seizing properties, which eases installation and removal
  • High grade alumina silicate ceramic insulator for dielectric performance
  • Solid 98% pure copper core for heat dissipation, conductivity and ultra wide heat ranges
  • Cold-rolled threads that help prevent cross-threading and cylinder head damage
  • Triple gasket sealing that prevents combustion gas leakage
