NGK Racing Spark Plug Box of 4 (BR8EG)

You're getting a box of four NGK BR8EG racing spark plugs. These are built tough for the demands of racing, with special designs on the center electrode to handle the heat and stress of competition. They're made to keep firing reliably even when things get intense on the track.

NGK uses a pure alumina silicate ceramic insulator here, which is strong and helps manage heat effectively. The special shape of the insulator nose is designed to improve how quickly the engine responds to throttle input. Plus, the copper core helps pull heat away from the plug, and the corrugated ribs on the insulator are there to prevent flashover, which is when the spark jumps to the wrong place instead of firing across the gap. The trivalent metal plating on the outside helps prevent corrosion and makes them easier to get in and out, which is always a plus during a race or rebuild.

These plugs are a solid option for a wide range of motorcycles and ATVs, including models like the Honda CR250R, Yamaha YZ250, and Suzuki RM250. Just remember to order four if you need a full set for your vehicle.
