RADIUM Engineering 20-0073-FL Catch Can Kit BMW Fluid Lock - E46 M3

The RADIUM Engineering 20-0073-FL is a complete oil catch can kit engineered specifically for the BMW E46 M3. This system protects your engine from elevated levels of crankcase blow-by that accumulate during aggressive driving, preventing oil-saturated air from circulating back into the intake and degrading performance.

Fluid Lock Technology:

This kit features RADIUM Engineering's patent-pending Fluid Lock technology. If the catch can fills up and is not emptied, an internal valve automatically closes to eliminate contaminants from exiting the catch can and entering the engine, while maintaining normal venting to prevent engine damage.

Key Features:

• Billet aluminum catch can with integrated dipstick
• Large 10AN ORB inlet/outlet ports for maximum flow
• 4AN ORB drain port for easy servicing
• 2-step oil separation baffling
• O-ring sealed construction safe for pressurized applications
• 7 fluid ounce capacity
• Laser-cut anodized E46-specific mounting bracket
• Mounts in RH engine bay compartment near firewall

Closed Loop System:

RADIUM Engineering's closed loop system does NOT vent to atmosphere, making it emissions and track legal. Clean filtered air routes back through the engine to be burned, promoting negative crankcase pressure for optimal performance while preventing unwanted oil vapors from entering the cabin.

Benefits:

• Effectively raises fuel octane and increases performance with cleaner intake air
• Prevents oil buildup in throttle body, intake manifold, and other components
• Lowers hydrocarbon emissions
• Excessive oil collection can indicate engine damage
• Stainless steel filtration media is cleanable and reusable

Complete Kit Includes:

• Fluid Lock catch can with integrated dipstick
• Laser-cut anodized aluminum E46-specific mounting bracket
• Anodized aluminum 10AN hose ends and adapter fittings
• 10AN (5/8") PCV hose (sufficient length for modified vehicles)
• Stainless steel mounting hardware

This kit is compatible with early E46 M3 models where the ABS module is mounted in the RH compartment, as well as later models with secondary PCV systems. LHD (left-hand drive) vehicles only.
