The NGK Ruthenium HX was developed for newer engines that require high ignition performance.
The dual fine electrode (DFE) design promotes concentration of spark energy and ignites over a wider range of air-fuel ratios, providing improved performance in rich or lean engine conditions.
The center electrode is made of 0.4 mm thick ruthenium alloy and the ground electrode is made of 0.8 mm thick platinum wire.
The trivalent metal platinum offers excellent corrosion protection and anti-seizing properties.
Corrugated ribs prevent rollovers.
The ram insulator made of pure aluminum oxide silicate ensures greater strength and better heat transfer.
Copper core helps dissipate heat.
