Radium Engineering Catch Can Kit PCV Subaru WRX VB Fluid Lock

The PCV catch can kit runs inline between the PCV valve and the intake manifold and promotes clean filtered air back into the engine. When the intake manifold pressure is close to or greater than atmospheric pressure, the PCV valve closes, and this hoses experience no flow. The PCV hoses will experience metered vacuum when the engine is idling, steady state cruising, and decelerating. This would normally draw unwanted crankcase vapor, unspent fuel, and oil sludge into the intake manifold immediately after a high load run. 

NOTES

• The catch can mounts to threaded bosses on the ABS unit.
• The PCV catch can kit is compatible and recommended to be used with the CCV catch can kit. See 20-0755-FL below.
• No extra inline check valve is required since Radium catch cans are pressure sealed.
