        What is your suggested gap or do these come pre-gapped? Or does the tune determine the gap?

        • These do not come pre-gapped, gapping will be based on your tune and application. We recommend discussing with your tuner directly.

        I have a 2006 GT with a 2008 motor with black boots.. I’m doing a turbo set up .. will these work ? I seen the other kind with brown boots . I’m not sure what the difference is

        • These spark plugs would be designed for the 05-08 GT Mustangs that are equipped with the black boots and would be compatible with a turbo set up. However, these spark plugs are ideal for Mustangs making up to 600 HP.

            Great plugs

            I bought these plugs to replace some auto lite ht0 plugs that I had been running. Nice to finally get those out and replace them with one piece plugs. These brisk units are very easy to gap unlike the ht0s that require a special tool. I would highly recommend these to anyone running a supercharged 4.6

            Awesome Impressed

            Finally upgraded from my og plugs on my modified supercharged mustang. Great plugs, noticed instantly the feel and response from moment I turned on the engine. My wife, not an engine or hp enthusiasts, mentioned how smooth it was while driving. Not giving full stars cause it been only a week installed. PS- they were recommended by Kenne-Bell while discussing an existing fuel issue...

            Spark plugs

            The plugs work very well no detonation on my pro charged mustang gt. They won't break in to like the factory ones do because they are one piece inside of the two piece design.

            Brisk Silver Racing Spark Plugs

            The are perfect for boost applications since now being a single turbo car they perform very well, and so easy to gap that's why they are rated high.

            If you're spuercharged or turbo'd, this is it!

            Had Ford Racing M-12405-3V0 plugs in my TVS supercharged 2007 427R. It's an upgraded SC with more boost on a built engine and so needed 1 heat range colder than stock, which these Ford plugs were. I drive hard, but not stupid. These began to fail and it took me a while to nail down the problem since they were still fairly new. Stumbling under load, etc. Switched to these Brisk and it was an instant fix. If you have a boosted 3V, get these! Unless you are running 15 PSI, in which case still go Brisk, one heat range colder. One less thing to worry about as these are the best! No more misses when into big boost at 6800 RPM!

            Seem to do the job.

            These plugs seem to do the job they were suppose to do. Had one of that wasn't working properly, called AM and they got another one to me no issues. My only problem with the plugs was how they were packaged. They were just thrown in a box with no packing and some had come out of their boxes and were banging around during shipping. Other than that all was good.

            Met Expectations

            I previously had Ford Racing plugs installed on my 2006 Kenne Bell Mustang GT. As other reviewers have mentioned, these Brisk plugs are easy to gap compared to the Ford Racing ones. I had about 30K miles on my Ford Racing plugs and decided to install these because Kenne Bell recommends them. Just be sure to add a small amount of anti-seize on the threads. Took a little longer than 1 hr to install because I struggled with so little room under my 130mm Kenne Bell throttle body above cylinder #4. The other 7 plugs went in quickly. No noticeable difference in horsepower. These Brisk plugs are very well made and would definitely recommend for forced induction cars.

            Brisk 450-599hp plugs

            I have an 06 GT with a Roush M90 and thought it was time to do away with the factory plugs. Paired these with MSD Blaster Coil Packs and saw a huge difference mostly in throttle response. Wasn’t noticeable in the seat of your pants but definitely smoother acceleration and quicker response, would recommend for modded mustangs!

            Im running a PD blower. These work great and came pre gapped at 0.30. Perfect for my SC application. They are also one piece and do not break when removing. These are my second set.

            Brisk

            After having spark issues with stock plugs with them not able to keep spark due to the amount of boost I put a set of the brisk plugs and gapped them to .030 degrees and there was an instant difference. I highly recommend these for boosted applications.
