V-Power Racing Plug 7942 .750in Reach- Ext Tip

The NGK V-Power Racing Plug 7942 with .750-inch reach and extended tip is a non-resistor spark plug engineered for high-performance racing and competition engines. This 14mm threaded plug with gasket seat design delivers reliable ignition in demanding conditions where consistent spark timing and thermal performance are critical to engine reliability and power output.

The .750-inch reach specification positions the electrodes at the optimal depth within the combustion chamber for engines designed to this standard, while the extended tip design improves heat range management and reduces fouling in high-RPM applications. As a non-resistor plug, the NGK R5672A-10 transmits full ignition voltage without suppression, making it ideal for carbureted and fuel-injected engines running aftermarket ignition systems that benefit from unfiltered spark energy. The gasket seat ensures a secure seal against combustion pressure without relying on a crush washer, providing consistent sealing across multiple heat cycles.

This plug is specified for vintage drag racing, oval-track competition, street performance builds, and precision carbureted engines where OEM ignition parameters have been modified or upgraded. Racing teams and engine builders rely on NGK's thermal and gap stability under sustained high-load operation. The V-Power series represents NGK's performance-focused manufacturing, combining durability with the electrical characteristics required in competition engines operating at elevated boost levels or high compression ratios.

NGK spark plugs are OEM-specified across major engine manufacturers and are recognized throughout the racing community for consistent quality and performance. Verify thread size, reach, and heat range compatibility with your specific engine before installation to ensure optimal combustion efficiency and engine protection.
