NGK Racing Spark Plug Box of 4 (R0465B-10)

NGK is a well-known name in ignition components, especially for their spark plugs used in motorsports. This R0465B-10 racing spark plug is built to handle the intense demands of competition. If you're pushing your engine hard, whether on the track or in a high-performance street application, these plugs are designed to keep firing reliably.

The center electrode on these NGK racing plugs features special designs aimed at ensuring both durability and consistent ignitability, even under extreme heat and pressure. They come in a variety of heat ranges, and this particular plug, part number 7506, is configured for demanding racing applications. The trivalent metal plating on the exterior helps prevent corrosion and seizing, making installation and later removal much easier. You'll also find corrugated ribs on the insulator to prevent flashover, and a copper core that's excellent at drawing heat away from the combustion chamber. Triple seals are used to ensure there are no leaks.

This is a box of four spark plugs. While these are designed for racing, they can be a solid option for any high-performance engine that requires a plug built for extreme conditions. Always refer to your vehicle's service manual or consult with a specialist to confirm the correct heat range and plug type for your specific application.
