The stock N54 BOV / bypass valves are often susceptible to wear and tear, leading to functional issues and leaks, preventing optimal performance. Turbosmart addresses this issue with their Kompact Plumb Back BOV kit. These performance BOVs offer greater boost response and no leaks and are easy to install and set up in just a matter of minutes.
The Plumb Back kit is designed fully recirculate excess compressed air back to the pre-turbo intake tubes.
All hardware and hoses required for installation are included in this kit.*
Installed in these BOVs are Green Springs rated to -15 InHg.
Easy to install and set up, the Kompact BMW Kit is an ideal performance upgrade for N54-engined twin-turbo BMWs (Z4 models require an additional pipe kit TS-0203-2001).
Application:
All current BMW 135i, 335i, 535i and Z4 with N54 twin turbo 3.0L engine.
