    • Hello! For a 150 shot of nitrous, I would probably steer more towards high boost plugs.

      Brisk silver plugs

      I installed a nitrous plate system with 125 shot and my car had the stock iridium tip plugs. Car just turned 20,000 miles so they were due to be changed. Talking with my engine builder he suggested the brisk plugs, one degree colder. Brisk has a larger tip and quality look. Noticeable difference in accelerating and work great with nitrous, highly recommended.

      brisk plugs

      Plugs came well package and fast shipping They did come pre gapped to .025 which is a little bit tight for the coyote motor but was easily regapped. Install was just like any plug change took my time about 45min. Engine runs like stock and are a must have with 150 shot of nitrous.
