Our new manifold pressure relief panel is yet another innovation by Speedtech Nitrous to provide the racer with the safest and best performing nitrous systems in the world. This reusable pressure panel will eliminate races lost at the line since it immediately resets from small backfires. No more stainless inserts to purchase either. Cars that use O2 sensors will benefit from the panel which have been known to backfire upon shutdown. The panel is excellent insurance to protect carburetors, throttle bodies and intake manifolds. These parts are fully CNC machined, anodized and o-ringed to seal the manifold.
