Blow-Off Valves & Diverter Valves for Turbo Cars

A blow-off valve (BOV) releases excess boost pressure from the intake tract when the throttle closes, protecting the turbocharger's compressor wheel from surge and delivering the signature venting sound that turbo enthusiasts love. Diverter valves recirculate the excess air back into the intake for a quieter, metered-air-friendly operation.

OneFastShop carries a wide selection of blow-off valves and diverter valves including atmospheric venting BOVs, recirculating diverter valves, dual-port hybrid valves, direct-fit OEM-replacement diverter valves, universal flange-mount BOVs, and vehicle-specific kits for sport compact, European, and American turbo platforms.

Every blow-off valve at OneFastShop ships brand-new with manufacturer warranty coverage. Whether you want the classic turbo flutter sound, a loud atmospheric vent, or a quiet recirculating upgrade over your factory diverter valve, OneFastShop has the right BOV for your setup. Shop the full blow-off valves collection today.
