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
