Running a dry-sump system on your BMW S54? Controlling crankcase vacuum is part of getting the setup right.
The VAC Motorsports S54 Dry Sump Vacuum Regulator Adapter bolts directly to the engine's valve cover, allowing a vacuum regulator to be connected so you can adjust crankcase vacuum to suit your build.
Properly regulated vacuum helps support oil sealing and prevent excessive vacuum. This adapter gives your S54 dry-sump setup a direct-fit connection for that adjustment.
