Radium Engineering PCV Catch Can Kit


Focus ST 2013-2018
Focus RS 2016-2018

Supplied exclusively by Radium Engineering, their catch can kit is the most functional and integrated system on the market. The catch can mounts using factory holes and integrates perfectly with the surrounding components. This Catch Can kit does NOT vent to atmosphere (VTA), and is emissions* and track legal. Closed loop systems remove the oil and sludge from the PCV gasses before it is routed to the engine to be burned. A closed loop system also promotes negative crankcase pressure for optimal performance. Furthermore, closed systems prevent unwanted oil vapors from entering the cabin. The dipsticks built into the catch cans allow easy inspection of accumulated fluid. No cutting, drilling or permanent modification to the vehicle is required.

This catch can runs inline with the PCV (positive crankcase ventilation) valve and retains it's factory function. When the intake manifold pressure is close to or greater than atmospheric pressure, the PCV "check" valve closes and, thus, this hose experiences no flow. Conversely, the PCV hose 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. Note: Because the Radium catch cans are pressure sealed, they are great for this boosted application so intake manifold connection is permitted.

Use the Catch Can Kit in conjunction with our optional Engine Block Breather plate PN 2363-OBP-AA for maximum performance. Select option when ordering.
