Radium Catch Can Kit for BMW E46 3-Series 1998-06 Fluid Lock 20-0073-FL

An oil catch can is essential on a performance vehicle to protect the engine from elevated levels of crankcase blow-by accumulated from aggressive driving. Excess oil saturated air circulating back into the air intake stream can lead to degraded performance.

Radium Engineering catch cans feature large 10AN ORB ports, a 4AN ORB drain port, 2-step oil separation baffling, and an O-ring sealed dipstick. 
 
Radium Engineering's closed loop system does NOT vent to atmosphere (VTA), thus is emissions and track legal. Instead, clean filtered air routes back in through the engine to be burned and to promote negative crankcase pressure for optimal performance.
Furthermore, a closed system prevents unwanted oil vapors entering into the cabin. This kit mounts in the RH side of the engine thus, it is not compatible with RHD BMW models.
