Radium Fluid Lock Catch Can Kit - BMW 335i/135i (N54)

Radium Fluid Lock Catch Can Kit - BMW 335i/135i (N54)

Application: BMW 135i, 335i and 535i (N54)
Part Type: Fluid Lock oil catch can kit
Part Number: 20-0373-FL

The Radium Fluid Lock Catch Can Kit for the BMW N54 separates oil and water condensation from crankcase gases before they reach the intake, preventing oil build-up in the intake, intercooler, throttle body and intake manifold. Cleaner inlet air raises effective octane and improves performance, and the closed system keeps oil vapour out of the cabin.

The kit mounts to the OEM power steering reservoir bracket with no cutting or drilling, and N54-specific billet 10AN adapters connect to the OEM vent tubing without modification. Radium's patented Fluid Lock design prevents the can from overfilling and holds collected fluid until it is emptied.

Key Features

• Fluid Lock: Patented design prevents overfilling and holds collected fluid
• Direct Fitment: Mounts to the OEM power steering reservoir bracket – no drilling
• N54-Specific Adapters: Billet 10AN adapters, no OEM vent tube modification
• Large Ports: 10AN ORB inlet/outlet, 4AN ORB drain
• 2-Step Baffling: Two-step oil separation
• Dipstick: O-ring sealed dipstick for easy inspection

What's Included

• Aluminium oil catch can with integrated dipstick
• Aluminium laser-cut BMW-specific mounting bracket

Optional Parts

• Radium Catch Can Petcock Drain Kit (20-0024) – Drain the can without removing the reservoir, where space allows

Important Notes

• There is no set emptying interval – check the dipstick from 3-4 weeks and adjust; PCV systems typically collect more than CCV systems
• Excessive collection can indicate an engine problem such as blow-by, an overfilled crankcase, poor breather placement or a PCV valve leaking under load
• The kit mounts to the power steering reservoir bracket on the front left-hand side of the engine bay – Radium does not state RHD fitment
• Installation instructions are available in the Instructions tab
