Product Description

The TiALSport 004028 Q Series 40 mm Recirculating Blow-Off Valve is a high-performance turbo accessory designed for universal turbocharged applications. With an adjustable 8-15 PSI spring range, this blow-off valve provides tunable boost venting characteristics to match a wide variety of turbo setups, whether on street or performance builds. Its recirculation design routes vented air back into the intake system, helping reduce compressor surge and maintain boost efficiency.
