radium ENGINEERING Catch Can Kit, PCV (2022 Subaru WRX)

The PCV catch can kit runs inline between the PCV valve and the intake manifold and promotes clean filtered air back into the engine. When the intake manifold pressure is close to or greater than atmospheric pressure, the PCV "check" valves close and, thus, this hoses experience no flow. Conversely, the PCV hoses will experience "metered" vacuum when the engine is idling, steady state cruising, and decelerating. This would normally draw unwanted crankcase vapor, unspent fuel, and oil sludge into the intake manifold immediately after a high load run.

The catch can mounts to threaded bosses on the ABS unit.

INCLUDES
-Baffled oil catch can
-WRX VB specific mounting bracket
-12AN adapter fittings and hose ends

-3/4" PCV hose

NOTES
1. The PCV catch can kit is compatible and recommended to be used with the CCV catch can kit.
2. No extra inline check valve is required since Radium catch cans are pressure sealed.
