The NGK Ruthenium HX High Ignitability spark plug brings advanced OE tip technology to newer engines that demand superior ignitability and life expectancy. It’s intended to improve starting, throttle response and idle quality. Patented ruthenium tips and specialized PSPE/DFE designs focus spark energy for a more complete burn. A fine 0.4mm ruthenium center electrode with a 0.8mm platinum ground, alumina ceramic insulator, corrugated ribs and trivalent plating provide durability, heat control and resistance to flashover.
