Radium Engineering Catch Can Kit for BMW E46 M3, Fluid Lock

Radium Catch Can Kit, BMW E46 M3, Fluid Lock

Application: BMW E46 M3 (2000-2006) and M3 CSL (2003-2004) – LHD only
Part Type: Fluid Lock oil catch can kit
Part Number: 20-0073-FL

The Radium Catch Can Kit for the BMW E46 M3 removes oil and water condensation from crankcase gases before they reach the intake, keeping oil out of the intake, throttle body and intake manifold. Cleaner inlet air can improve performance and lower hydrocarbon emissions, and the closed system keeps oil vapour out of the cabin.

The can mounts in the RH engine bay compartment near the firewall and suits both early models with the ABS module in this compartment and later models with a secondary PCV system. Radium redesigned its 7 fl oz catch can in 2022 with the patented Fluid Lock system, which stops the reservoir from overfilling and traps collected fluid until the can is emptied.

Key Features

• E46 M3 Specific: Mounts in the RH engine bay compartment near the firewall
• Patented Fluid Lock: Prevents overfilling and holds collected fluid until emptied
• Direct Fit: No drilling required
• 10AN ORB Ports: Inlet and outlet
• 4AN ORB Drain Port: Optional petcock drain kit available where space allows
• Two-Step Baffling: Two-stage oil separation
• O-ring Sealed Dipstick: Check the fluid level easily
• Capacity: 207 ml (7 fl oz)

What's Included

• Billet aluminium catch can with integrated dipstick
• Laser-cut anodised E46 mounting bracket
• Anodised aluminium 10AN hose ends and adapter fittings
• 10AN (5/8in) PCV hose – enough for modified vehicles
• Stainless steel mounting hardware and hose clamps

Important Notes

• LHD only – not compatible with right-hand-drive vehicles, as the can mounts in the RH engine bay compartment near the firewall
• Compatible with early models with the ABS module in this compartment and later models with a secondary PCV system
• Empty by unscrewing the lower reservoir, or fit a petcock drain kit where space allows
• Emptying interval varies by vehicle – check the dipstick from 3-4 weeks and adjust from there; PCV cans typically collect more than CCV cans
• Excessive oil collection can indicate an engine issue such as excessive blow-by, overfilled oil, poor breather port placement or baffling, or a PCV valve sticking open under load
• Installation instructions are available in the Instructions tab
