Radium CCV Fluid Lock Catch Can Kit, Subaru WRX VB (2022+)

The Radium Engineering 20-0755-FL CCV Fluid Lock Catch Can Kit is a purpose-built crankcase ventilation solution for the Subaru WRX VB (2022+). Running inline between the crankcase vent (CCV) port and the turbo inlet pipe, this kit intercepts oil-saturated blow-by before it accumulates in the air filter intake pipe and intake system — protecting the FA24F engine from oil contamination under high-load driving.

The catch can mounts underneath the OEM air intake duct using factory holes — no cutting, drilling, or permanent modifications required. It is fully compatible with the OEM air duct. The kit is a closed-loop design — it does not vent to atmosphere (VTA), making it emissions compliant and track legal.

Note: This kit addresses the CCV side only. It does not address blow-by from the PCV side of the crankcase. For complete coverage, pair with the Radium 20-0754-FL PCV Catch Can Kit, or see the Radium 20-0756-FL Dual Kit for both circuits in one purchase.

CCV Circuit

At low loads, the CCV circuit sees atmospheric pressure. Under high load (WOT), it experiences high flow from the crankcase into the intake system — conditions that would normally deposit oil and sludge in the air filter intake pipe, turbocharger, and intercooler. The Radium catch can captures these contaminants and routes clean filtered air back into the intake, promoting negative crankcase pressure for optimal performance and preventing oil vapours from entering the cabin.

Key Features

• CCV circuit coverage — inline between valve cover CCV port and turbo inlet pipe
• Fluid Lock design — prevents fluid from draining back into the engine when the can is full
• Large 10AN ORB ports — maximise flow and minimise restriction
• 4AN ORB drain port — easy, clean draining without removing the can
• 2-step oil separation baffling — highly effective at separating oil mist from blow-by vapour
• O-ring sealed dipstick — check fluid level without opening the system
• Closed-loop system — emissions compliant and track legal, no VTA
• WRX VB-specific mounting bracket — mounts under OEM air intake duct using factory holes
• OEM air duct compatible — no clearance issues with factory duct
• No permanent modifications required — no cutting or drilling
