    High Powered Performance. Keep your Mustangs high powered 3-valve 4.6L 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 Brisk Silver Racing spark plugs are designed for use in Mustangs that are making 600 or more 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.

    what should these be gaped at?

    • Ideal plug gap will depend on a number of factors. We recommend starting near the stock gap of 0.045", however cars with upgraded ignition system components such as the coils, can increase this gap. Turbo and supercharged cars may need to adjust the gap further depending on boost levels.

      Much needed

      My 06 is running just over 600hp and the stock plugs just won’t work needed these colder plugs for the car to run appropriately.

      Brisk spark plugs

      Plugs were nice and you could set the gap with a regular feeler gauge. No special tool.
