About this part

Product Details

NGK is well-known for making reliable ignition components, and their Racing spark plugs are built to handle the toughest conditions you can throw at them. These plugs are designed specifically for racing applications where extreme heat and pressure are common. The center electrode features special designs to ensure it holds up over time and ignites the fuel mixture reliably, even under intense demands.

You'll find these plugs offer ultra high performance across a range of heat ranges, thanks to their special configurations tailored for various racing needs. The copper core inside helps pull heat away from the combustion chamber, and the corrugated ribs on the insulator help prevent flashover, which is crucial for consistent spark delivery. Plus, the trivalent metal plating on the exterior provides excellent resistance to corrosion and seizing, making installation and removal much easier when it's time for maintenance.
