Radium Engineering Catch Can Kit CCV WRX VB Fluid Lock

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.
