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.
