    What is considered low boost?

    • Low boost will be relative to your specific setup, but generally feel free to contact us or your tuner directly for a recommendation on a specific set of spark plugs!

    I have a 2012 GT 5.0, can the brisk silver racing plugs be used on non force inducted stock 6 speed mustang. thank you.

    • These Brisk Silver Racing Spark Plugs could technically be used on a naturally aspirated application as long as the spark plugs are gapped correctly.

      Solid Product

      I have put 300 miles with these plugs in. Took less than an hour to install including the time to remove intake pipe for supercharger. Good stuff.

      Running with my VMP

      Installed these with my VMP blower. They are recommended by VMP to prevent early detonation. I don't have any issues, so they work.

      Works Great

      I purchased these plugs during a supercharger install on my 13 Boss 302. These are the only plugs I have used with the blower, so I can not say they are better than anything else out there. That being said, my tuner was very happy with my setup and the load values from my data log. He made a comment on how well the car was running, so the plugs must work well under mild boost. All eight plugs came gapped at .025-.028 My setup is a 2013 Boss 302, Kooks headers, Paxton 2200 with stock pulley and a 7700 RPM redline.

      Awesome product

      These are the best plugs you can buy. Price isn't bad. Silver electrode is the way to go if you have a supercharger.

      Brisk plugs taking care of business

      I have never heard of this brand before but after some research I decided to give em a try. They showed up fast from American Muscle and only one needed a slight gap adjustment. They went into my '11 Vortech powered coyote and made her sing. The tips on these look like they will last a lot longer than the other brand they replaced. Still in process of logging and tuning but so far I'm liking them.

      Well worth it!

      These plugs have a much faster responce than my old stock ones, I most definitely noticed the difference! I'm at 566rwhp and 7 lbs of boost, I gapped them at .32 and love every minute of it!

      The product I ordered was great! They made the stand run better with the new procharger set up! I couldn't ask for a better product and company to buy from. I love American Muscle!!
