      Faster Times. Purge your nitrous lines of air and stale nitrous for faster times with this Nitrous Express purge kit. This kit allows you to prime your system before a run, plus it can be used to depressurize your lines before removing your bottle. This kit is a must-have for any serious racer with a nitrous system.

      Purge Cloud Effect. "Snow" the crowd with the impressive effect of a cool nitrous purge cloud. Purging your lines before a run is an impressive way to make an entrance - and is a great way to get the respect your Mustang deserves.

      Application. The Nitrous Express purge kit is offered with a -4 AN (aka D-4 or 1/4" NPT) manifold to run inline with your nitrous feedline, allowing it to be used even on solenoids without purge ports.

        NX does not disappoint

        Great product, purchased along with the Nitrous kit and the Pressure gauge. All amazing, this purge kit hooked right up with no issue on my car. Awesome carbon fiber finish and works great. I recommend this product for those looking to add a purge kit to their vehicle.

        Purge kit install

        The product is great quality. The discharge line could be longer. I like that it was easy to install. I would advise anyone to use this set up.

        Get ya purge on!

        Helps keep my line full of nice nitrous instead of old stale air. Bad thing is the kit comes with a short piece of tube. Go to auto zone an buy a 3 foot piece of 3/16 aluminum gas line. It comes with the threaded insert so just Teflon tape it an screw it in an now you can route it anywhere!
