Collection: Auto - Turbocharger Blow Off Valve

Safely vent excess charge-pipe pressure, completely eliminate compressor surge flutter, and protect your turbo’s internal bearings from catastrophic deceleration shock with our precision selection of Auto Turbocharger Blow Off Valves (BOV). At DIY Customs, we provide high-performance blow-off valves, specialized recirculating bypass valves, heavy-duty external wastegates, charge pipe adapters, and adjustable pressure spring kits designed for a perfect fit on turbocharged and supercharged engines. Whether you are seeking an atmospheric blow-off valve to get that iconic crisp venting sound on a modified track machine, outfitting your shop bay with a heavy-duty recirculating valve to satisfy engine computer airflow expectations on a modern European or domestic street vehicle, or replacing a leaking factory diaphragm valve to completely clear up frustrating high-boost power loss, our professional-grade forced induction accessories offer the rapid pressure response and sealing security you need at unbeatable prices. From raw vacuum line adapters and aluminum weld-on flanges to direct-fit bolt-on upgrade assemblies, we carry the ultimate pressure-management essentials to protect your forced induction loop.
