    20421-10 is rated 4.6 out of 5 by 5.
    Rated 5 out of 5 by from Spray This kit is awesome. You will probably need an adapter to attach the fuel pickup line to your fuel rail, if you are installing this on a stock fuel injected vehicle. This kit is designed to utilize the vehicles already present fuel system to provide fuel augmentation. The kit would work with a carburated engine too, if you were interested in a single nozzle set up. You may need to purchase additional jets to get it right though. The NX website has an easy to understand chart to help you figure out the jetting. Plan on measuring and knowing for sure what your fuel pressure actually is under load, this is how you will determine jetting. This was my first nitrous kit, and i am addicted!

    Rated 5 out of 5 by from An honest review.. I purchased this kit assuming it wasn’t going to be that great since it’s pretty cheap, I received free ground shipping, 8-10 business days. So u waited and received my kit within 4 business days and obviously I was looking forward to this kit. Once I saw the package at home I ripped up the package and everything was in better condition than expected. I really enjoy this kit and I will most definitely continue purchasing from Jegs.

    Rated 3 out of 5 by from Almost complete set Kit has ALMOST everything one would need to set up nitrous kit. A 500 dollar kit doesn't come with the fuel rail adapter when the kit is advertised to utilize it.

    Asked by: lowcat
    The NX 744-20421-10 is a universal nitrous kit. This should work on the Charger.
