        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

        4 2006 GT - GGutierrez Installation Time: Afternoon

        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.

      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.

      My 2008 4.6l is making 440 crank hp which puts me really close to the 450hp rating on these plug so my question is will the colder plugs be ok at this hp? I’m running H1plugs now but plan on a pro charger in the near future.

      My 2008 4.6l is making 440 crank hp which puts me really close to the 450hp rating on these plug so my question is what is the difference between these plugs and the up to 450 hp plugs and will it be better for me to use these plugs or the less hp plugs. I’m running H0 plugs now?

      What is the pre-set gap on these?

      • These do not come pre-gapped.
