The Mishimoto baffled oil catch can kit for 2013+ Ford Focus ST uses a 2-port compact can with internal baffling and a 50‑micron bronze filter to trap oil and fuel vapors from the PCV system. The kit includes direct-fit hoses, a serviceable mounting bracket near the oil drain plug, CNC aluminum fittings, and is intended to reduce carbon buildup on direct-injection engines while remaining user-serviceable.
