RR10S Silver Racing Spark Plug

The Brisk Silver Racing RR10S spark plug is engineered for optimal performance in tuned and race engines, as well as vehicles utilizing alternative fuels such as CNG, LPG, Propane, E85, Alcohol, LNG, Race Fuels, and Nitro. Its construction features a smaller diameter silver core and a conventional open spark hook type earth electrode, which provide superior ignition of high-octane fuel mixtures. Silver's excellent thermal and electrical conductivity allows for rapid heat dissipation, resulting in a lower spark plug temperature and a more powerful spark. This stronger spark promotes a faster and better flame front and flame speed, contributing to a smoother higher RPM range in engines. The RR10S is compatible with most aftermarket and OEM ignition systems, from simple coil and distributor setups to modern direct ignition systems. Key specifications include a 14mm thread diameter, 25mm thread reach, 16mm (5/8") hexagon, tapered seat, and a heat range of 10. The plug utilizes a 1.5 mm silver wire center electrode and is designed to fire properly even if fouling occurs, a common failure point for standard plugs. It also requires a lower voltage and can reduce wear on coils, leads, and other ignition components. Popular applications for the Brisk RR10S include the 2011-20 Ford Mustang 5.0, 2011 Chevy Camaro V6, and GEN 3 HEMI Engines (5.7L, 6.1L) found in Dodge SRT 4, SRT 8, HEMI, and Chrysler 300 models. The service life is rated for 30,000 km (18,000 miles) or 50 hours of racing.
