NGK Racing Spark Plug Box of 4 (R7282-10)

If you're building a high-performance engine for the track, getting the ignition system dialed in is crucial. These NGK Racing spark plugs, part number R7282-10, are built specifically to handle the intense demands of racing. They're designed to provide reliable spark even under the most grueling conditions, helping your engine perform at its peak when it matters most.

NGK puts a lot of thought into their racing plugs. The center electrode features special designs to ensure it holds up over time and fires consistently. You'll also find that the corrugated ribs on the insulator help prevent flashover, which is when the spark jumps to the wrong place instead of firing in the cylinder. The copper core is there to help pull heat away from the combustion chamber, and the triple seals are there to make sure you don't have any leaks.

This set comes with four plugs, which is what most 4-cylinder engines will need. Remember to check your vehicle's specific requirements for the correct heat range and gap setting before installation.
