Nitrous Express Nitrous Purge Valve (4AN Manifold Push Button and Vent Tube)

The NX Purge System includes a Lightning  purge solenoid and a 4AN manifold, push button and vent tube. Purging the air out of your nitrous line allows harder launches and quicker 60ft times, which in turn, can shave up to 2 tenths off of your quarter mile ETs.
