RUTHENIUM HX™
High-Ignitability Spark Plugs
Ruthenium HX™ brings the most advanced spark plug technology to the automotive aftermarket, delivering better efficiency and power for today’s engines.
- HIGH IGNITABILITY PROJECTED SQUARE PLATINUM ELECTRODE DESIGN: Combines 0.6 millimeter ruthenium center with a unique cut-back PSPE ground electrode
- PSPE DESIGN: Projected square platinum electrode shape of the ground electrode provides the best ignitability and service life for high heat engines
- RECOMMENDED USAGE: Modern vehicles using OE PSPE type spark plugs or for those seeking an aftermarket plug with the latest OE technology
- RUTHENIUM ALLOY CENTER ELECTRODE: NGK's patented ruthenium technology produces maximum performance, ignitability & durability at high temperatures
- SOLID COPPER CORE: 98% pure copper core offers superior heat dissipation, conductivity and ultra wide heat ranges
- TRIVALENT METAL PLATING: Delivers superior anti-corrosion and anti-seizing properties, ensuring ease of installation and removal
THE NGK DIFFERENCE
Superior oxidation resistance
Advanced high-ignitability technology
Enhanced blistering/anti-peeling
NGK Ruthenium HX is designed for newer engines which demand high ignitability. Projected Square Platinum Electrode (PSPE) 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.
