NGK is known worldwide for powering racing champions, and their Racing Series spark plugs are built to handle the toughest conditions you can throw at them. This B9EG SOLID plug is designed specifically for extreme use, ensuring reliable ignition even when your engine is pushed to its limits. The center electrode features special designs to maintain durability and consistent ignitability, bringing ultra-high performance across a variety of heat ranges suitable for many racing applications.

These plugs feature a trivalent metal plating that resists corrosion and seizing, making installation and removal much easier.
