Brisk Silver Racing Spark Plug

The Brisk RR10S is a Silver Racing spark plug engineered for high-performance and racing applications. Its design utilizes silver, the best thermal and electrical conductor, for its core electrode. This results in superior heat dissipation, a lower spark plug temperature, and a more powerful spark, leading to faster flame front propagation and an improved higher RPM range. The plug features a 1.5mm silver fine wire center electrode and a tapered ground electrode, along with a special high dielectric strength insulator. It is specifically recommended for engines with 16+ lbs of boost or a 175+ shot of nitrous, and is 3-steps colder than standard plugs. These spark plugs offer lower required supplied ignition voltage, which is beneficial for easier cold starts and operation under conditions like prolonged idling, A/F management issues, or oil consumption. They are also advantageous when the stock ignition system is pushed to its limits, potentially eliminating the need for an ignition system upgrade. The RR10S is designed to fire properly even when fouling occurs, a common failure point for standard plugs, and can reduce wear on coils and leads. It is suitable for a wide range of applications including tuned and race engines, alternative fuel vehicles (CNG, LPG, E85, alcohol, race fuels, nitro), high RPM racing, and both naturally aspirated and forced induction setups. Key specifications include a 14mm thread diameter, 25mm (1") thread reach, 16mm (5/8") hexagon, tapered seat, and a heat range of 10. The service life is rated for 30,000 km or 18,000 miles, and 50 hours of racing. This spark plug is a popular choice for the 2011-20 Ford Mustang 5.0, 2011 Chevy Camaro V6, and GEN 3 HEMI Engines (5.7L, 6.1L) found in Dodge SRT vehicles and Chrysler 300 models.
