NGK Ruthenium HX Spark Plug (MPN: 94279)

Advanced spark plug technology for enhanced engine performance and efficiency.

The NGK Ruthenium HX Spark Plug is engineered for modern engines that require high ignitability and performance. Its Double Fine Electrode design enhances spark energy concentration, allowing for ignition across a broader range of air-fuel ratios. This results in improved engine performance under both rich and lean conditions, making it a reliable choice for various driving scenarios.

Featuring a 0.4mm Ruthenium alloy fine wire center electrode and a 0.8mm platinum fine wire ground electrode, this spark plug offers superior oxidation resistance and durability. The trivalent metal platinum coating ensures excellent anti-corrosion and anti-seizing properties, while the corrugated ribs effectively prevent flashover, enhancing overall reliability.

The pure alumina silicate ceramic insulator provides exceptional strength and efficient heat transfer, complemented by a copper core that aids in heat removal. Manufactured in an ISO 11565-certified facility, the NGK Ruthenium HX Spark Plug represents the forefront of spark plug technology, delivering better efficiency and power for today's automotive engines.
