These Brisk Silver Racing spark plugs are designed for use in Mustangs that are making 450 to 599 horsepower at the flywheel, perfect for Methanol injection, Forced induction and Nitrous applications.

Superior Design and Materials. Brisk Silver Racing spark plugs feature a high dielectric strength insulator and use a 1.5mm fine wire silver center electrode for its excellent electrical and thermal conductivity which in turn produces a more powerful spark. The tapered ground strap design allows for superior ignitability on hard to ignite fuels minimizing the chance fouling.
