This is the Radium Engineering PCV Fluid Lock Catch Can Kit. Catch can kits are essential to Subaru platforms to protect the engine from elevated levels of crankcase blow-by accumulated from aggressive driving. Excessive oil-saturated air circulating back into the air intake stream can lead to degraded performance. The Radium Engineering catch can kit features large 10AN ORB ports, a 4AN ORB drain port, a 2-step oil separation baffling, and an O-ring sealed dipstick.
