        Brisk spark plugs

        Customer service suggested the brisk to me and I couldn't be happier with the noticeable difference. Got them in a few days nicely packaged. Thanks A.M. Install not bad once supercharger intake side was removed.

        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.

      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.
