        Brisk plugs

        My wife’s mustang was missing when you hit the gas so I thought I would try these plugs I wanted 1 piece plugs and these are great it fixed the problem but getting the old two piece plugs out is a Challenge.

        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.
