The SPARK PLUG BR9EG from NGK’s Racing Series is designed to endure the most demanding engine environments, ensuring reliable ignition and consistent performance. Its specialized insulator nose configuration enhances throttle response, providing sharper acceleration and smoother power delivery. Corrugated ribs on the insulator effectively prevent flashover, maintaining stable spark integrity under high voltage conditions. Crafted from pure alumina silicate ceramic, the insulator offers exceptional strength and efficient heat transfer, critical for protecting against overheating. The copper core further aids heat dissipation, improving plug longevity and engine efficiency. Triple sealing technology ensures no leakage, preserving optimal combustion for peak engine performance in racing scenarios.
