Product Description

The TiALSport 004727 QRJ 40 mm Recirculating Blow‑Off Valve is a universal turbo accessory designed for engines that require smooth and tunable boost venting back to the intake system. With a 6 PSI internal spring, this blow‑off valve offers a balanced boost release suitable for many street and performance setups. Its CNC‑machined aluminum body and black anodized finish deliver durability and corrosion resistance while keeping weight low.

Featuring a modular design with configurable inlet and return ports and a responsive banjo‑style air fitting with an oversize hose barb, the 004727 can adapt to a variety of intake and turbo layouts. The recirculation capability helps maintain intake efficiency while reducing compressor surge, and its compact size allows installation in constrained engine bay spaces. Because this part is universal, verify flange compatibility and routing requirements for your specific turbo system before installation to ensure optimal fit and performance.
