Description
Radium Dual Catch Can Kit, 15-18 Ford Focus ST, Fluid Lock
Application: Ford Focus ST 2015-2018 (2.0L EcoBoost)
Part Type: Dual (PCV + CCV) catch can kit
Part Number: 20-0358-FL
A catch can separates oil and water condensation from crankcase gases before they reach the intake, preventing oil build-up on the intake, intercooler walls, throttle body and intake manifold. Cleaner intake air helps effective octane and performance, and the closed system keeps oil vapour out of the cabin.
The 20-0358-FL dual kit combines the PCV kit (mounted on the front LH core support near the radiator) with the CCV kit (mounted at the back LH side of the engine bay) for the 2015-2018 Focus ST. Fluid Lock is Radium's patented catch can design that stops the reservoir overfilling and holds collected fluid until it is emptied.
Key Features
- Dual Protection: PCV can on the front LH core support plus CCV can at the back LH side of the engine bay
- Fluid Lock Design: Radium's patented Fluid Lock mechanism stops the reservoir overfilling and holds collected fluid until it is emptied, so contaminants can't spill back into the intake
- Large Ports: 10AN ORB inlet and outlet ports with a 4AN ORB drain port
- Efficient Separation: 2-step oil separation baffling
- Easy Checking: O-ring sealed dipstick shows how much fluid has been collected
- Capacity: 207ml (7 fl oz)
- Direct Fitment: No drilling required

Important Notes
- Requires the 20-0356 Sound Symposer Block-Off (or another symposer delete kit) – sold separately
- Radium's fitment listing does not specify RHD/LHD – please contact us to confirm fitment on Australian-delivered vehicles
- There is no fixed emptying interval – check the dipstick after 3–4 weeks of driving and repeat as needed (PCV cans generally collect more than CCV cans)
- Empty by unscrewing the lower reservoir, or fit the optional Petcock Drain Kit where there is room under the can
- Excessive oil collection can indicate an engine problem such as excessive blow-by, an overfilled sump, poor breather port placement/baffling or a PCV valve leaking under load
