Product Details

This is a box of four NGK Ruthenium HX spark plugs, part number FR6AHX-S. These plugs are designed for modern vehicles that require high ignitability, offering an updated tip technology for improved performance and a longer lifespan. They feature a patented Ruthenium alloy fine wire center electrode and a platinum fine wire ground electrode, which work together to concentrate spark energy and ignite a wider range of air-fuel mixtures. This can lead to a more complete fuel burn, resulting in quicker throttle response, a smoother idle, and better cold starts. The corrugated ribs on the insulator help prevent flashover, and the copper core aids in heat removal. These plugs fit a wide range of vehicles, including many models from Acura, Audi, and BMW.

The Ruthenium center electrode is known for its industry-leading durability, and the plugs also include a pure alumina silicate ceramic insulator for superior strength and heat transfer. For added protection against corrosion and seizing, they come with a trivalent metal plating. These are a solid option if you're looking for an aftermarket plug that incorporates the latest OE technology for your vehicle.
