The Nitrous Express nitrous flo-thru 4AN swivel manifold is a billet aluminum manifold that swivels on one end to simplify attachment without turning the whole body, useful with NX Lightning 45 bottle valves. It provides two 1/8 NPT ports so you can add a nitrous gauge, a fuel pressure gauge, or other 1/8 NPT accessory inline with a 4AN nitrous feed for convenient monitoring and accessory integration.
