Fitment Information

2022+ Subaru WRX


The Radium Engineering 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.

Radium Engineering catch cans feature:

  • Large 10AN ORB ports
  • 4AN ORB drain port
  • 2-step oil separation baffling
  • O-ring sealed dipstick

These kits mount using factory holes and integrate perfectly with the surrounding components. They do NOT vent to atmosphere (VTA), thus are emissions and track legal. Closed loop systems remove the oil and sludge from the PCV gasses before it is routed to the engine to be burned. A closed loop system also promotes negative crankcase pressure for optimal performance. Furthermore, closed systems prevent unwanted oil vapors from entering the cabin. The dipsticks built into the catch cans allow easy inspection of accumulated fluid. 

What is included?

  • Baffled oil catch can
  • WRX VB specific mounting bracket
  • 12AN adapter fittings and hose ends
  • Stainless steel hardware
  • 3/4" inch PCV hose


1. The PCV catch can kit is compatible and recommended to be used with the CCV catch can kit, which is available to purchase separately (rad20-0755-FL), or as a full kit (rad20-0756-FL).

2. No extra inline check valve is required since Radium catch cans are pressure sealed.

Install Note

The catch can mounts to threaded bosses on the ABS unit. No cutting, drilling or permanent modifications are required.
