The NGK R6254K-105 is a racing spark plug designed for high-performance, extreme conditions. It features a pure alumina silicate ceramic insulator for superior strength and heat transfer, a solid copper core for excellent heat dissipation and conductivity, and trivalent metal plating for anti-corrosion and anti-seizing properties. The design also includes corrugated ribs to prevent flashover, a low angle tip for durability in racing, and triple seals to prevent leaks.
- Designed for Racing: Engineered to withstand extreme heat and vibration.
- Insulator: Made from high-grade alumina silicate ceramic for increased strength and better heat transfer.
- Copper Core: A solid 98% pure copper core promotes superior heat dissipation and electrical conductivity.
- Trivalent Metal Plating: Provides enhanced anti-corrosion and anti-seizing properties for easier installation and removal.
- Corrugated Ribs: Prevents flashover, which is an electrical arc that can cause misfires.
- Triple Seals: A sealing process that helps prevent compression leakage from the spark plug.
- Low Angle Tip: A design specifically for racing to improve ignitability under extreme conditions.
- Cold-Rolled Threads: Helps prevent cross-threading and damage to the cylinder head.
- Heat Range: Rated at a 10.5 heat range, indicating its ability to operate effectively in a high-heat environment.
