NGK Ruthenium HX is designed for newer engines which demand high ignitability. Double Fine Electrode (DFE) design promotes spark energy concentration and ignites a wider range of air-fuel ratios, offering improved performance in rich or lean engine conditions.

  • 0.4mm Ruthenium alloy fine wire center electrode and 0.8mm platinum fine wire ground electrode
  • Trivalent metal platinum provides superior anti-corrosion and anti-seizing properties
  • Corrugated ribs prevent flashover
  • Pure alumina silicate ceramic insulator provides superior strength and better heat transfer
  • Copper core aids in heat removal
  • MPN: LFR6AHX-S
