The Nitrous Express nitrous purge valve with poly line (6AN) is part of the NX purge system that includes a Lightning purge solenoid, a 6AN manifold, a push button and vent tube. Purging trapped air from nitrous lines helps produce harder launches and quicker 60-foot times, making this valve and its plumbing useful for drivers seeking crisper launch behavior from a nitrous-equipped car.
