Dual Catch Can Kit for Subaru WRX 2022+ Fluid Lock Radium Engineering
Compatibility
Overview
Radium Engineering catch cans feature large 10AN ORB ports, a 4AN ORB drain port, 2-step oil separation baffling, and an O-ring sealed dipstick.
The kits mount using factory mounting points and integrate seamlessly with surrounding engine components.
The closed-loop system does not vent to atmosphere (VTA), making it emissions and track legal. It removes oil and sludge from the PCV gases before they are routed back into the engine for combustion. The system also promotes negative crankcase pressure for improved performance while preventing unwanted oil vapors from entering the cabin.
The integrated dipstick allows for easy inspection of collected fluid.
20-0754-FL Catch Can Kit, PCV, Subaru WRX VB, Fluid Lock
The PCV catch can installs inline between the PCV valve and the intake manifold, returning clean, filtered air back into the engine.
When the intake manifold pressure is close to or greater than atmospheric pressure, the PCV check valve closes and no flow occurs through the hose. During idle, steady-state cruising, and deceleration, the PCV system experiences metered vacuum, preventing crankcase vapors, unburned fuel, and oil sludge from entering the intake manifold after high-load driving.
Includes
- Baffled oil catch can
- WRX VB-specific mounting bracket
- 12AN adapter fittings and hose ends
- Stainless steel mounting hardware
- 3/4-inch PCV hose
20-0755-FL Catch Can Kit, CCV, Subaru WRX VB, Fluid Lock
The CCV catch can mounts beneath the factory air intake duct without requiring any permanent vehicle modifications.
To retain factory functionality, the CCV catch can installs inline between the crankcase ventilation (CCV) port and the turbo inlet pipe.
At low engine loads, the system experiences atmospheric pressure. During wide-open throttle (WOT), high crankcase flow would normally carry oil and sludge into the turbo inlet and intake system. The catch can captures these contaminants and returns clean, filtered air to the intake.
Includes
- Baffled oil catch can
- WRX VB-specific mounting bracket
- 10AN adapter fittings and hose ends
- Stainless steel mounting hardware
- 5/8-inch PCV hose
