Silver Racing RR14S Spark Plug

The Brisk Silver Racing RR14S spark plug is engineered for demanding performance applications, including those using alternative fuels like E85, CNG, and race fuels. Its design incorporates a smaller diameter silver core and a conventional open spark hook type earth electrode, which contribute to outstanding performance by efficiently igniting high-octane fuel mixtures. Silver's superior thermal and electrical conductivity allows for faster heat dissipation, resulting in lower spark plug temperatures and a more powerful spark. This stronger spark promotes faster and better flame front propagation, leading to smoother operation at higher RPM ranges. Key specifications include a 14mm thread diameter, 25mm thread reach, 16mm hexagon size, and a tapered seat. The plug features a heat range of 14 and a 1.5 mm Silver Wire Centre Electrode. It is designed with a resistor and is non-projected. The advanced design reduces voltage requirements and can lessen wear on ignition components like coils and leads. This spark plug is recommended for tuned and race engines, alternative fuel vehicles, older vehicles with weaker ignition systems, and high RPM race engines. Popular applications 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. It is also compatible with 2014+ GM LT Engines and various EcoBoost applications.
