NGK Racing Spark Plug Box of 4 (R7433-9)

If you're pushing your engine to its limits on the track, you need spark plugs that can keep up. These NGK Racing spark plugs are built specifically for those grueling racing conditions where reliability and consistent spark are critical. They're designed to handle the intense heat and pressure that come with high-performance driving, helping to ensure your engine runs strong when it matters most.

What sets these plugs apart is their special center electrode design, which is made for durability and reliable ignition even under extreme stress. The corrugated ribs on the insulator help prevent flashover, a common issue in high-performance engines, while the copper core works to pull heat away from the combustion chamber. Plus, the trivalent metal plating on the exterior makes installation and removal easier by resisting corrosion and seizing, which is a practical detail when you're working on a race car.

This is a box of four plugs, so make sure you check how many cylinders your engine has to order the correct amount. They're a solid option for anyone serious about racing and needing dependable ignition performance.
