This Nitrous Express extreme nitrous purge valve with 6AN manifold, push button and vent tube is supplied as a full purge system including a Lightning purge solenoid. The kit is intended to purge air from nitrous lines to enable harder launches and quicker 60-foot times; the manufacturer indicates this approach can reduce quarter-mile ETs by as much as two tenths in suitable setups.
