Description
Radium Engineering Dual Catch Can Kit - Subaru WRX VA 15+/FXT SJ 13-18 (FA20) - Fluid Lock
Application: Subaru WRX VA 2015-2021 and Forester XT SJ 2014-2018 (FA20F)
Part Type: Dual Fluid Lock catch can kit (PCV and CCV)
Part Number: 20-0256-FL
The Radium Dual Catch Can Kit keeps oil and sludge out of the intake tract, intercooler and intake manifold of the FA20F-powered WRX and Forester XT. Being direct injected, the FA20F has no port injectors to wash the back of the intake valves, making oil vapour control especially important on stock and modified street cars.
The forward can captures the CCV line contents and the rear can captures the PCV line contents. The system is fully sealed, retains factory PCV valve function and is rated for boosted applications, for cleaner intake air and less oil vapour reaching the cabin.
Key Features
- Dual Can System: Forward can on the CCV circuit, rear can on the PCV circuit
- Fluid Lock Design: Patented Fluid Lock system prevents the reservoir overfilling and holds collected fluid until emptied
- Direct Fitment: Bolts in with no drilling required
- Large Ports: 10AN ORB inlet and outlet ports with a 4AN ORB drain port
- Two-Step Baffling: Two-stage oil separation baffling
- Integrated Dipstick: O-ring sealed dipstick for checking the collected level
- Boost Rated: Pressure-sealed cans permit intake manifold connection on boosted engines
- Factory PCV Function: Sealed system retains the factory PCV valve operation
What's Included
- Radium Fluid Lock catch can (x2)
- Anodised aluminium mounting bracket
- ORB to AN flare fittings
- Push-lok hose ends

- Hose clamps and stainless steel mounting hardware
Optional Parts
- Radium Catch Can Petcock Drain Kit (20-0024) – allows the can to be drained without removing the lower reservoir, where there is space underneath
Important Notes
- Not compatible with the Subaru WRX STI
- Not compatible with some Sport Lineartronic (CVT) models, which have a control module where the cans mount – compare the install location with your engine bay before ordering
- Radium has not tested this kit on right-hand-drive models – please contact us to confirm fitment before ordering
- May not be compatible with some aftermarket intake systems
- There is no fixed emptying interval – check the dipstick from 3–4 weeks of driving and adjust from there; excessive collection can indicate an engine issue such as blow-by, overfilled oil or a PCV valve leaking under load
- Installation instructions are available in the Instructions tab
