Engineered for extreme conditions with advanced ignition technology.
NGK Racing Spark Plugs are specifically designed to endure the most demanding engine environments. These plugs feature a unique V-Cut in the center electrode that directs the spark to the edge, enhancing ignitability and reducing quenching for improved performance. The special insulator nose configurations contribute to better throttle response, making them suitable for high-performance applications.
The trivalent metal plating offers superior anti-corrosion and anti-seizing properties, ensuring longevity and reliability. Additionally, the corrugated ribs are engineered to prevent flashover, while the pure alumina silicate ceramic insulator provides exceptional strength and heat transfer capabilities. The copper core further aids in efficient heat removal, maintaining optimal operating temperatures.
With triple seals designed to prevent leakage, these spark plugs are a robust choice for racing and non-automotive applications. The NGK Racing Spark Plug is a single unit that combines advanced materials and engineering to deliver consistent performance under pressure.
