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. This oil catch can kit is compatible with all BMW 135i, 335i, and 535i models with the 3.0L twin turbo N54 engine. Review the installation instruction link above before ordering.

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'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.

The kit secures to the OEM power steering reservoir mount with no cutting or drilling required. As shown, this kit includes N54 specific billet 10AN adapter fittings eliminating the need to modify the OEM vent tubing.
