Silver Racing Spark Plug

The Brisk Racing Silver Spark Plug (RR14S) is engineered to unlock an engine's full potential, particularly for high-octane and alternative fuel applications including CNG, LPG, Propane, E85, Alcohol, LNG, Nitro, and Race Fuels. The plug utilizes a 1.5mm silver wire center electrode, which is the best material for a core electrode due to its ability to dissipate heat quickly, resulting in a lower spark plug temperature and a more powerful spark. This stronger spark leads to a faster and better flame front and flame speed, promoting a smoother higher RPM range in engines. The Silver Racing range is compatible with most aftermarket and OEM ignition systems, from simple coil and distributor setups to modern electronic and direct ignition systems. Technical specifications include a 14mm thread diameter, 25mm (1") thread reach, 16mm (5/8") hex size, and a tapered seat. It features a Silver Racing design, a resistor for interference reduction, and a non-projected tip. The heat range is rated at 14, with silver as the material for the center electrode. This spark plug is ideal for tuned and race engines, alternative fuel vehicles, high RPM performance engines, and standard and high-compression engines. It is also beneficial for older vehicles with weaker ignition systems or excessive oil consumption. The service life for these spark plugs is rated up to 30,000 km (18,000 miles) or 50 hours of continuous racing. Popular applications include 2014+ LTx Engines, 2011–2020 Ford Mustang 5.0, and GEN 3 HEMI 5.7L / 6.1L / 6.4L engines (Dodge SRT-4, SRT-8, HEMI, Chrysler 300). Brisk RR14S spark plugs have been instrumental in setting world records in extreme performance applications.
