Description

The NGK LKR6AHX is a Ruthenium HX spark plug designed for high ignitability in modern vehicles. It features a patented Ruthenium technology with advanced tip design for optimal performance and extended life. The spark plug offers a more complete fuel burn, leading to quicker throttle response, smoother idle, and better cold starts.

Constructed with a 0.4mm Ruthenium alloy fine wire center electrode and a 0.8mm platinum fine wire ground electrode, this plug provides superior durability. It also includes trivalent metal platinum for anti-corrosion and anti-seizing properties, corrugated ribs to prevent flashover, and a pure alumina silicate ceramic insulator for strength and heat transfer. The copper core aids in heat removal.
