    I have a highly modified 2006 Mustang GT with the original spark plugs and black coil boot. Can I use the Blaster coil boots with these (they are red)?

    • The Brisk Silver Racing Spark Plugs are compatible with the MSD Blaster Coils.

    Will these go well with a turbo mustang gt 08

    MiguelP

    • These Brisk Silver Racing Spark Plugs work great with all high performance applications including force induction motors. These are rated for 450-599HP which is ideal if your Turbo is creating that much power at the flywheel.

    What are the details of the "BLACK" coil boot rule? I have the red MSD coil boots and have been running these plugs for a couple of years. Please inform me and the rest of the community about the details of the black coil boot rule.

    JasonP

    • It has to do with the year of compatibility. I'd like to point how the spark plugs are cut-off in the middle of 2008, so these only fit 08s manufactured in the first half of that year. Right in the middle of that year Ford decided to change the coil boots, which affected the fitment. So, if you don't have black coil boots, you probably have a later-half 2008 Mustang.

    06 GT, what type of anti seize (if any) and what torque spec? Thanks

    Roush3v

    • The Brisk Silver Racing Spark Plugs should be torqued to 25 LB Ft, applying high temperature nickel anti-seize lubricant to only the spark plug ground electrode shield (the part between the tip and the threads)

      Brisk plugs

      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.

      I had a problem with high RPM spark being blown out, but no longer an issue with these plugs. Great product, I would recomend these plugs to anyone with a boosted application.

      Excellent Spark Plug's

      I have tried Several options of Spark plugs on a 4.6 Turbo Charged 3 Valve Mustang and I have too say these plugs perform far better than the Autolite HTO. The 1 one piece design will save you time and money because they won't break off in the cylinder. I have had Multiple Issues with the porcelain at the tip coming apart or the porcelain on base of plug coming loose and moving slightly causing a very difficult misfire too detect being all plugs are new and was unable too see this on a Cylinder Contribution Test. Spend the Extra Money and buy Brisk Spark Plugs they are worth every dollar. Excellent Product!

      05 GT with Brisk plugs

      My car is mildly modified with just over 480 rwhp and these plugs work great. They are much easier to gap than the autolight ht0 and I have no complaints. AM also sells them much cheaper than any where I found online and they came fast as always. Can't beat AM.

      Great Addition

      The idea of plugs that won't break when removed is fantastic but then add in a plug with a common electrode that is a breeze to gap and you have a winner! the gain in performance is hard to realize without going back on the dyno however it smoothed out a low end problem I was experiencing after adding on a Whipple S/C.

      The plugs, they are 'a changin'

      Love the one piece design, hopefully no more wincing on the first few turns of the wrench next changeout. Electrodes are muuuuuch easier to gap.

      Peace of Mind

      I'm driving an M90 Roushcharged 427R with 103,000 miles (daily driver), so I've been through a few sets of plugs. I started with the Autolite HT0's, and have used the Ford Racing equivalent a few times. After reading about the Brisk plugs, I decided to go with them on my last plug change. On a first drive, the performance seemed to be about the same as the Autolites and the Ford Racing plugs, so there has (so far) not been a "night and day" difference. Car is still in "learning mode" after disconnecting the battery, so maybe there is a "gain" coming that has not hit yet, but at this point, no complaints. But, here is where I think the Brisk plugs are light years ahead of the Autolite HT0 and Ford Racing: 1. Brisk plugs are a single piece design, as opposed to the two-piece design of the other plugs. 2. Traditional design electrode for easy plug gapping (versus the "stirrup" electrode of the other plugs, which is nearly impossible to gap correctly without a special $30 tool). Right away, the one piece design gives me piece of mind, and I don't have to worry about the plug coming apart on removal. Just go ahead and read the horror stories about this on the 2005 to early-2008 4.6 L Mustangs (black coils), and that should sway you to the Brisks by itself. Just to be safe, I did use the Nickel Anti-Seize anyway for extra insurance. And, finally, a standard electrode I can easily gap to .035 (out of the box, mine were gapped at about .040). We'll see how they do on the long run!
