Nitrous Express Nitrous Flo-Thru Manifold (4AN) Swivel

Cheap manifolds trap nitrous and create inconsistent delivery — the flo-thru design keeps the circuit live and pressure stable across the system. The 4AN swivel takes the guesswork out of line routing, letting you clock the fitting to suit your setup without fighting the plumbing. At this price point, it's the sensible choice over generic fittings that compromise your tune.
