The dramatic purge effect that people have come to love is now availiable at a fraction of the cost of other systems on the market. They can be used as a vent to a CryO2 system or as a stand alone show system. Must be used with a CryO2 Tank and Install kit (#080100 or #080102). The purges come in single or dual vents and the supply line can be split multiple times for multiple bursts around the car. You can also use the purge system seperate from the CryO2 performane system buy utilizing the purge kits that includes a solenoid vave and extension hose. This set-up will seperate the performance from the show purge.
