When you're building a high-speed racer for the streets or the strip, you don't always want to give away what's under the hood. People have won plenty of pink slips by tricking challengers into underestimating their capabilities. And, one of the best ways to fly under the radar is with the Turbosmart Plumb Back Blow Off Valve.
The Turbosmart Plumb Back lets you blow off steam without blowing your cover. Unlike atmospheric blow off valves that scream bloody murder every time you max out on boost, it recirculates excess pressure back into your intake-all while muffling your turbo's telltale chirp. Perfect for off-road rally racers and rides with touchy air-flow systems, the Plumb Back's fully sealed design blocks crud from breezing into your system.
No matter what type of sleeper you're sitting behind, there's a universal Turbosmart Plumb Back BOV that's sure to fit. They're carved from rock-solid billet aluminum, and come with a quick-release V-band clamp and weld-on adapter for a DIY install. You also get to pick between several whoosh-worthy finishes-both are backed by a 1-year warranty.
