Set of 4 Spark Plugs

Generally when onespark plug fails that means the rest will also fail soon. We recommend you change all spark plugs at once. That way a month later you won’t be running a cylinder short because one of your otherspark plugs failed.

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. DFE (double fine electrode) maximizes ignitability, while reducing emissions for low-heat engines. This NGK-patented design is recommended for non-turbo applications.

Features and Benefits:

• 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
