Product Description

The TiALSport 004026 Q Series 40 mm Recirculating Blow-Off Valve is a universal performance component designed for turbocharged engines that require both effective boost pressure control and smooth recirculation of vented air back into the intake tract. With its larger 40 mm valve diameter and adjustable 8-20 PSI spring range, this blow-off valve provides tunable response characteristics that suit a variety of turbo setups and performance goals, from mild street builds to higher-boost applications.

Constructed from CNC-machined aluminum and finished in black anodization, the 004026 delivers durability and corrosion resistance while keeping weight down. It includes a V-band clamp and weld flange for secure installation, plus a banjo-style air fitting with an oversized hose barb for rapid actuator response. The recirculation port allows clean routing back into the intake system for turbo efficiency and reduced compressor surge. Always confirm flange compatibility and proper boost range tuning for your specific turbo system before installation to ensure optimal performance.
