The NGK Ruthenium HX spark plug deploys patented Ruthenium tip designs to achieve high ignitability and exceptional longevity for modern engines. Double Fine Electrode configurations focus spark energy for more complete combustion, improving throttle response, idle quality and cold starts. NGK complements this with an alumina ceramic insulator, corrugated ribs to prevent flashover and trivalent plating to reduce corrosion and ease service life demands.
