Radium Catch Can Kit PCV Fluid Lock 2022+ Subaru WRX

Fitment Information 2022+ Subaru WRX Features 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
