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: LKAR6AHX
