Our new Manifold Pressure Relief Valve is yet another innovation by Nitrous Pro Flow to provide the racer with the safest and best performing nitrous systems in the world.This reusable pressure relief valve will eliminate races lost at the line since it immediately resets for small backfires This keeps you on the track after a backfire, rather than having to replace a burst panel.Naturallv aspirated engines can benefit from this technology as well, particularly when using O2 sensors which often cause a backfire upon engine shut-down The panel features a 1.25" hole that allows for the venting of excessive pressure whether it is from a nitrous backfire or a naturally aspirated hiccup. The part is excellent insurance to protect expensive carburetors, throttle bodies and intake manifolds. The parts are fully CNC machined, anodized and o-ringed to seal to the manifold.
