Description
Radium Fluid Lock Catch Can Kit - BMW 135i / 335i / 535i (N54)
Suits:
- BMW 135i — E82 / E87 / E88 (N54, 3.0L Twin Turbo)

The Radium Engineering Fluid Lock Catch Can Kit is engineered specifically for the BMW N54 twin turbo engine. The kit secures to the OEM power steering reservoir mount with no cutting or drilling required. N54-specific billet 10AN adapter fittings are included, eliminating the need to modify the OEM vent tubing.
This is a closed loop system — it does not vent to atmosphere (VTA), making it emissions compliant and track legal. Clean filtered air routes back through the engine to promote negative crankcase pressure for optimal performance, while preventing unwanted oil vapours from entering the cabin.
- Capacity: 7 fl oz
- Height (without fittings): 5"
- Outside Diameter: 2.45"
- Ports: 10AN ORB inlet/outlet, 4AN ORB drain
- Filtration: Stainless steel media — cleanable and reusable

Benefits
