The ground electrode is cut-back from the center electrode to provide a gap, and its concave face ensures a constant gap for optimal performance. This design opens the spark face for better ignitability of the flame kernel, retains less heat, and transfers heat to the shell faster, significantly reducing the risk of pre-ignition. Dyno testing has shown proven power gains, making this plug ideal for all aftermarket cylinder heads used in various racing venues, including oval and road racing. Featuring a gasket seat type, this spark plug is engineered to handle intense conditions and deliver superior performance.
