The BMS vacuum side N54 OCC works in conjunction with our world-famous boost side N54 oil catch can to prevent engine oil and PCV gunk from coating your intake valves and hurting engine efficiency under engine vacuum operation. Our boost side OCC separates oil traveling through the PCV while the engine is operating under boost pressure (e.g. heavy throttle) and our vacuum side OCC separates oil traveling through the PCV while the engine is operating under vacuum (idle and low throttle). When used together they provide the ultimate protection keeping oil from coating your intake ports and valves during all phases of engine operation!

Our unique PCV adapter design does not require you to permanently cap/plug your PCV holes! Includes a high-performance check valve that attaches directly to the vacuum source eliminating boost leaks within the system and also includes quick connect fittings and 3/8” hose for quick, easy, and clean installation.

The full kit includes a BMS double baffle OCC which mounts on the strut brace right next to your BMS boost side OCC for a clean look and easy service. The full kit also includes our BOV adapter providing an extra 1/8" NPT vacuum port source. Note a BOV is not required to run this kit. This kit eliminates the need for a separate RB PCV or BMS PCV.
