            WORKS WITH N/A MOTORS

            There is a lot of controversy with these plugs. Did some research and digging around, spoke with Brisk directly, These spesificaly (3VR17YS) work perfectly fine with N/A motors, they said even totally stock these are a great option but work well with even light modifications. Call them and ask yourself 713-459-6977. So the 2 big questions I needed answered that hopefully help you: YES they work with your stock 3v and .035 gap.

            Stop the hesitating !

            So after several mods and quite a long experience driving my ride (142,000 Miles) she began to stutter when I accelerate, and if I pushed the gas to the floor, it strait up would pause, hesitate then proceed forward. Just overall garbage. I purchased these plugs figuring the reviews also stated that others had the same problem and these plugs solved it. WOW THEY DID.....This is like a car right off the show-room now, completely all her power regained, all the acceleration and pep that she once had is all back. These work great on even lightly modded cars. Just buy them, Don't buy the OEM Ford ones, Just don't do it. Buy these. Please. Save yourself.

            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!!

            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.
