Nitrous Pro Flow Manifold Pressure Relief Valves

Nitrous Pro Flow manifold pressure relief valves provide the racer with the safest and best performing nitrous systems in the world. These reusable valves eliminate races lost at the line, since they immediately reset for small backfires. This keeps you on the track after a backfire, rather than having to replace a burst panel. Naturally aspirated engines can benefit as well, particularly when using O2 sensors, which often cause backfire upon engine shutdown. The panel features a 1.25 in. hole that allows for the venting of excessive pressure, whether it is from a nitrous backfire or a naturally aspirated hiccup. They're excellent insurance to protect expensive carbs, throttle bodies, and intake manifolds. Pro Flow pressure relief valves are fully CNC-machined, anodized, and O-ringed to seal to the manifold.
