Catch Can Kit, BMW 335i/135i N54 with Petcock Drain Kit

This oil catch can kit is compatible with all BMW 335i and 135i 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.
