High Powered Performance. Is your high powered GT Mustang experiencing misfires because of weak or fouled plugs? Then you need to upgrade to a set of Brisk Silver Racing Spark Plugs to keep your Pony running smoothly and more efficiently. Brisk designed these Silver Racing Series Spark Plugs especially for those Mustangs that are making up to 450 horsepower at the flywheel. These Brisk Plugs will provide constant reliable spark power and are perfectly suited for 3-valve 4.6L V8 engines that are running a forced induction setup, nitrous or methanol injection.

Superior Design and Materials. Featuring a high dielectric strength insulator, Brisk Silver Racing Spark Plugs are manufactured with a 1.5mm fine wire silver center electrode for its excellent electrical and thermal conductivity to produce a more powerful spark. To minimize the chance fouling Brisk Spark Plugs feature a unique tapered ground strap design that allows for superior ignitability, even on hard to ignite fuels.

Application. This set of eight (8) 12MM Thread Brisk Silver Racing Spark Plugs are specifically designed for the 2008-2010 GT and Bullitt Mustangs equipped with Brown coil boots only.

    Had 1 go bad prematurely.

    I was pleased with them until my car started to missfore past 3000 rpms and backfiring. Started troubleshooting woth the obvious coil packs and plugs. Found cylinder #2 spark plug having the core tip moving loosely. Changed it out and car ran fine. Only had them on the car for less than a year and less than 6000 miles. I guess this things happen, but even the stock motorcrafts did not go bad this quick. I will be changing all of them out shortly to prevent this from happening sometimes soon.
