Description
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.
Product Overview
NGK Ruthenium HX High Ignitability spark plugs are the best in class plug for todays modern vehicles. Patented Ruthenium technology offers the most advance tip technology and delivers the highest performance and life expectancy. Created from advanced OE technology as a high ignitability plug; Ruthenium HX spark plugs come with patented, specialized OEM DFE and PSPE tip designs. NGK Ruthenium HX High Ignitability spark plugs provide a more complete fuel burn resulting in a quicker throttle response, smoother idle and better cold starts. Ruthenium center electrode provides industry leading durability.
