Turbo Blow Off Valve Aluminium for VW/Audi 1.8T 2.7T

Turbo Blow Off Valve Aluminium for VW/Audi 1.8T 2.7T

Enhance throttle response and turbo efficiency with this aluminium Turbo Blow Off Valve (BOV1173) crafted for VW and Audi 1.8T and 2.7T applications. Made from T6 aviation-grade aluminum with a hard anodized finish, it replaces the OEM plastic diverter valve to deliver more precise, consistent pressure release while standing up to heat and wear. This recirculation valve redirects charged air back into the intake rather than venting to the atmosphere, helping prevent turbo stall and maintain smoother power delivery across shifts.

Designed for straightforward installation and reliable performance, it combines 100% tested quality assurance with a robust construction that protects the turbine and boosts overall engine response. The valve offers a choice of spring pressures to tailor boost behavior to your setup, along with spacers to fine-tune spring pressure as needed.

Originating from Mainland China, this valve is built to withstand demanding driving conditions while providing a notable upgrade over factory diverter valves. Vehicle compatibility charts are for reference only. Check your OEM specifications to match your needs.
