An oil catch can is essential on a performance vehicle to protect the engine from elevated levels of crankcase blow-by accumulated from high performance driving. Excess oil saturated air circulating back into the air intake stream can lead to degraded performance.

2013+ Focus EcoBoost Catch Can Kit Details:

Radium Engineering catch cans feature large 10AN ORB ports, a 4AN ORB drain port, 2-step oil separation baffling, and an O-ring sealed dipstick. These kits mount using factory holes and integrate perfectly with the surrounding components. These two oil catch cans (PCV side and Crankcase side) function completely independent of each other and are sold individually or together. They do NOT vent to atmosphere (VTA), thus are 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.

Dual Catch Can Kit (P/N 20-0328 and 20-0358)

The two catch can kits (PCV and crankcase) mentioned above can be purchased together using part numbers 20-0328 (Focus RS) or 20-0358 (Focus ST).

This kit can be used to remotely drain the catch cans without the need to unscrew the canister body. One kit per catch can. Radium recommends this kit for the PCV side catch can, as this is the side that will see the most oil accumulation.
