Aluminium Turbo Blow Off Valve for VW and Audi 1.8T/2.7T
The Aluminium Turbo Blow Off Valve for VW and Audi 1.8T/2.7T is a high-performance BOV designed to replace the OEM plastic diverter valve. By recirculating charged air back into the turbo inlet, it prevents compressor surge and turbo stall when boost is released, delivering quicker throttle response and smoother downshifts. Crafted from durable T6 aviation-grade aluminum with a hard anodized finish, this valve withstands demanding boost environments while maintaining a polished, race-ready look.
Built for a wide range of VW and Audi turbo engines, including the 1.8T and 2.7T families, this unit is engineered for reliable operation and easy installation. It strengthens the pressure release torque to protect the turbine and extend the life of the turbocharger. The design is 100% tested for quality assurance, offering sensitive response without breaking the bank. External testing certification is ISO9000. For 2.7L bi-turbo applications, two valve sets are required to achieve proper operation. Vehicle compatibility charts are for reference; please verify with OEM specifications to match your needs.
