Product Information

Full recirculating BOV. The Plumb Back system recirculates all excess pressure back into the intake system. Great for enthusiasts not wanting to be noticed but wanting the performance and reliability benefits of a quality BOV.

Please note; that for twin-turbo applications, such as the Audi S4 2.7L (B5) 97-01, this will require two valves.


Supplied With:
Green Spring Rated -15 InHg (installed)

Turbo quality has been at the forefront of every decision we have ever made, a fact that was recognised in 1990 when we became the first British turbo remanufacturing company to be awarded the ISO 9001 certification. Today, it still remains the case, and that is why we carry out work for the majority of the OE manufacturers. We were responsible for the design of many of their quality system processes. From the design of our rigorous testing processes, to the choice of our brand partners, we are committed to delivering the very highest standard of quality of turbos, spares and advice to our customers.

ISO 9001 is an international Standard that acts as your guarantee that you will receive the same level of quality assurance and service from AET as you would do if you were dealing directly with the manufacturer.

All our turbo units except competition units carry a 12-month warranty. AET Turbos recommend fitting a new oil feed pipe and the use of high quality synthetic/semi-synthetic oil, which should be changed according to manufacturer’s recommendations or every 6,000 miles if no guidance is available. Please see our terms and conditions for further information.

We send fitting instructions with every turbo dispatch.
