NGK Ruthenium HX spark plugs are designed for newer engines which demand high ignitability. Double Fine Electrode (DFE) engineering promotes spark energy concentration and ignites a wider range of air/fuel ratios, offering improved performance in rich or lean engine conditions. Order the plugs recommended for fitment on your application.

Additional details:

* 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 i
