High Powered Performance. Keep your nitrous or forced inducted Mustangs high powered Coyote 5.0L V8 engine running smoothly and more efficiently with a brand new set of Brisk "Silver Racing" series spark plugs for a constant reliable spark power. These RR14S Brisk Silver Racing spark plugs are specifically engineered for use in 5.0L V8 Mustangs that are running mild nitrous or a medium boost supercharger or turbocharger setup.

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.

  • Hello! For a 150 shot of nitrous, I would probably steer more towards high boost plugs.

    brisk plugs

    Plugs came well package and fast shipping They did come pre gapped to .025 which is a little bit tight for the coyote motor but was easily regapped. Install was just like any plug change took my time about 45min. Engine runs like stock and are a must have with 150 shot of nitrous.

    Brisk silver plugs

    I installed a nitrous plate system with 125 shot and my car had the stock iridium tip plugs. Car just turned 20,000 miles so they were due to be changed. Talking with my engine builder he suggested the brisk plugs, one degree colder. Brisk has a larger tip and quality look. Noticeable difference in accelerating and work great with nitrous, highly recommended.
