The NX Purge System is designed to purge the air from your nitrous lines to allow immediate activation of your nitrous system. This System includes a Lightning solenoid, push button for activation, and a vent tube to direct the purged nitrous out of the solenoid. Also included is a manifold to run inline with your nitrous feedline. This allows you to purge the nitrous system, even when you do not have a purge port built into your solenoids. The Purge system can also be used to lower the bottle pressure for spot on nitrous performance every time you activate the system.
