The Garrett GVB-50A 50mm VTA blow-off valve in silver is a 50mm vent-to-atmosphere valve designed to release compressor surge pressure in turbocharged intake systems. Installed between the turbo and throttle, it vents excess boost to atmosphere on throttle closures. Use this silver GVB-50A when a 50mm VTA-style valve with that finish suits the vehicle’s turbo plumbing and sound preference.
