    Hello, I have a slightly modded 2006 GT with a cold air intake, headers and a full exhaust system and a tune. However i bought it from a guy whi had no clue about the tune and had no idea how much power the car made. So my question is should i go for these spark plugs or stick to the oem plugs. thank you for your time!

    • Since the vehicle is equipped with a handful of aftermarket components, you may want to consider upgrading to some lower temperature spark plugs for better performance and efficiency.

    Doing an N/A build on my 07 GT would I be able to install these plugs as well as a set of MSD blasters without having to gap them?

    • We recommend checking the gap on the Brisk Silver Racing Spark Plugs and adjusting as needed to ensure your vehicle performs properly with good driveability.

      Happy with the Brisk spark plug option

      Fixed my engine sputtering! I just purchased my car and the previous owner never replaced the spark plugs, so they were in shocking condition when we pulled them out. It has fixed the engine sputtering and happy they are good up to 450HP, saves any hassle to replace them again if adding HPs.

      No more misfires. I bought these with the MSD coil boots. It runs and accelerates like a new car. I had no idea spark plugs and boots make such a difference.

      Great Plugs

      Gotta 2006 4.6L Mustang GT convertible and have been disappointed with original Ford fouling out at about 25K and online forums recommending colder Autolite 0 plugs which I installed about 30k. This is my daily driver, so no strip starts, some freeway speeds and few long distance drives. Well got misfires in several cylinders over periods and talked to the American Muscle folks after reading numerous Mustang reviews and the leader was Brisk Silver racing plugs. Fit was same and easy. Like the normal open electrode that I can confirm Gap rather than previous sealed, closed electrode. I noted immediate correction of the misfires and increased performance. Great start of response and performance noted in passing speeds, and overall peppiness. Only in several weeks so cant comment on mpg increase. Love these plugs so far. Afternoon installation mainly in care pulling other plugs out as plugs could separate in head....lots of Power Blaster overnight and careful extraction and a little more careful installation per online horror stories.

      Nice upgrade!

      These go in nicely gapped at oem spec. WARNING the old ones do not come out so easily. I did mine with a hot motor and some PB blaster. Work em out slowly! Back and forth.. It's not the threads it's the fit below them.. Take your time!!

      Awesome plugs

      What a great plug to upgrade to. Also got a set of MSD coil packs to go with them and it ran so much smother. Now I don’t have to worry about breaking the plug in the head

      Brisk Racing Spark Plugs

      Replaced spark plugs with a second set of Brisk Racing spark plugs after 80,000 miles. Gapped at .045”. Installation took 30 minutes. 2005 Mustang GT runs smooth and strong even with 200,000 miles. Great plugs. Highly recommended.

      Great Purchase

      I was installing a supercharger when I decided I needed to have these spark plugs, (for some reason you spend that much on a "kit" for a supercharger, but do not get supercharger spark plugs to go along with the "kit".) These plugs have been great, I have had no issues with them currently, while running about 575 to the flywheel.

      Awsome Spark plugs.

      Yes get the block hot and then don't forget some sea foam deep creep. Did both and didn't snap any old plugs. These plugs are very nice and work well

      ONE PIECE

      Bought these to replace my worn out motorcrafts. I had four of those stupid two piece plugs snap off and these brisks are one piece so common sense prevailed. Was able to gap them with no issues. Car running great now

      Overall good plug

      Real nice upgrade from stock, hardest part is removing the old plugs. Make sure to get the engine block nice and hot before trying to remove old plugs to help reduce the chance of breaking the plugs in the block. I did it cold and snapped 5 of em, luckily I had the tool to remove the broken plugs.
