EVO 8-9 75MM THROTTLE BODY - RED

This Boomba Racing adjustable blow-off valve (BOV) adapter mounts between the OEM bypass valve/solenoid and the stock turbo (or charge pipe if 1.5L), venting unused charge air to the atmosphere for a distinct turbo sound. It bolts in with included longer bolts, requiring no other modifications or tuning. Precision CNC machined from aircraft-grade billet aluminum, it features nine threaded holes for adjustability, shipping with 3 open. A 2mm Allen key is included for fine-tuning by adding or removing screws to control venting/recirculation. This adapter is constructed from high-quality materials and enhances the BOV sound.
