4AN Nitrous Single Outlet Purge Kit

The Cold Fusion Nitrous 4AN Single Outlet Purge Kit is designed for racers who demand a clean, consistent nitrous system and want the unmistakable visual impact of a massive purge cloud.

A purge system removes air trapped in the main nitrous feed line between the bottle and the front of the vehicle. Clearing that trapped air helps minimize delays and surges when the system is activated, helping deliver more consistent nitrous operation at the track.

The kit features a .078" nitrous orifice engineered to produce a massive purge cloud, while the 5 feet of flexible high-pressure purge line gives you the freedom to position the outlet where it works best for your combination.

Designed to fit any make, model, or year vehicle, this is a straightforward way to add professional purge functionality and race-day presence to your nitrous system.
