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 offers several completely independent oil catch can kits for the Evo 8-9 that are sold individually or together using the menu above. All kits work with the OEM strut bar. The first type do NOT vent to atmosphere (VTA), thus are emissions and track legal. Closed loop systems route clean filtered air back in through the engine to be burned and to promote negative crankcase pressure for optimal performance. Furthermore, closed systems prevent unwanted oil vapors into the cabin. The Crankcase VTA kit does not recirculate crankcase gasses back through the engine and is intended for race vehicles dealing with a large amount of blow-by gasses.
