Radium Catch Can Kits | 2022+ Subaru WRX (20-075)

2022+ Subaru WRX Catch Can kit by Radium Engineering

Radium Engineering catch cans feature large 10AN ORB ports, a 4AN ORB drain port, a 2-step oil separation baffling, and an O-ring sealed dipstick. These kits mount using factory holes and integrate perfectly with the surrounding components. They do NOT vent to the 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. No cutting, drilling, or permanent modifications are required.

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, these hoses experience no flow. Conversely, the PCV hoses will experience a "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.

Without making any permanent modifications, the CCV catch can mount underneath the OEM air intake duct. To retain factory functionality, the CCV catch can run inline between the crankcase vent (CCV) port and the turbo inlet pipe. At low loads, it experiences atmospheric pressure. However, when the engine is at high load (WOT), the line will experience high flow from the crankcase into the intake system. This would normally lead to oil and sludge accumulation in the air filter intake pipe. The CCV catch can capture this and promotes clean filtered air back into the intake.
