    Rated 5 out of 5 by from Great kit Does anybody know the part no. For the plate in the kit? Got a tunnel ram and need another plate exactly like it. Ordered a NP404 but not for sure if it’s gonna be the same or not

    Rated 5 out of 5 by from Works great Put this system on my 496 84 Monte Carlo just for fun. Works great! I took my time installing it and bought some extras (nitrous pressure guage and a wide open throttle switch instead of the button in the kit). I also ran -4 fuel line so I didn't use the barbed fitting that came with it. I pled 4 degrees trimming and put in a couple gallons of race gas, then put in the 100hp jets. Works perfectly and plugs look great after spraying it. Buy it and a couple extras, you will love it.

    Does the solenoids on this kit work with methanol applications?

    Asked by: CampbellRacing3X3X
    No, this kit is not designed for nitrous applications, you will need this kit - https://www.jegs.com/i/Nitrous-Express/744/30045-10/10002/-1
