NGK Racing Spark Plug Box of 4 (R7376-8)

If you're working on your 2004 Kawasaki KX125 and need spark plugs that can handle serious abuse, these NGK Racing spark plugs are a solid option. They're built specifically for the demands of racing, where consistent ignition and durability under extreme heat and pressure are critical. NGK has a long history in racing, and these plugs are designed to perform when it matters most.

The center electrode on these plugs features special designs to ensure they last and fire reliably, even in the toughest conditions. They come in a variety of heat ranges, so you can pick the right one for your specific engine setup. The trivalent metal plating helps prevent corrosion and seizing, making installation and removal much easier down the road. Plus, the pure alumina silicate ceramic insulator offers superior strength and helps transfer heat away from the plug effectively, while the corrugated ribs prevent flashover. A copper core further aids in heat removal, and triple seals ensure there are no leaks.
