Purge kits remove any air that may have become trapped in the main feed line between the bottle and the front of the vehicle that can cause delays or surges in your nitrous system. Removing the trapped air pockets results in improved 60 ft and ET at the track and prevents back fires from too much fuel. Our purge kits have a .076" nitrous orifice that creates a massive cloud of nitrous anytime our nitrous purge kit is activated. This system will fit any make, model, and year vehicle. Five feet of flexible high pressure purge line allows for you to place the purge outlet just about anywhere on your vehicle.
