Nitrous Express Burst panels allow for pressure relief upon the occurrence of a backfire. These reusable valves use an o-ring seal on the burst panel and to seal on the manifold, which allows them to be added to almost any sheetmetal or cast aluminum manifold. No need to replace a burst panel after a backfire as the springs will automatically reset after each backfire. The panel features a 1.5 in. hole that allows for the venting of excessive pressure, whether it is from a nitrous backfire or a naturally aspirated hiccup. These are very cost effective insurance to protect carburetors, throttle bodies, and intake manifolds.
