    1 Top Rated Question

    I recently ordered a Nitrous plate kit, I was wondering what size do these plugs come pre-gapped? and also what size should I gap them to if need be for a 150 shot plate kit on my 2013 GT.

    • The Brisk Silver Racing Spark Plugs for high boost applications does not offer the specifications on the gap from the manufacturing plant, however, most boost applications will require .028 to .032 gap. You will still want to consult with your tuner for the proper gap, for your specific application.

      Great plugs

      Boost was blowing out the spark on the Ford racing plugs, these solved the problem instantly.
