The NGK Ruthenium HX High Ignitability spark plug leverages patented ruthenium tip designs and a Double Fine Electrode to focus spark energy for more complete combustion. That yields quicker throttle response, smoother idle and improved cold starts on modern engines demanding high ignitability. Ruthenium fine-wire electrodes and alumina ceramic insulation provide long life, while trivalent plating resists corrosion and seizing.
