MISHIMOTO Ford Fiesta ST Baffled Oil Catch Can, 2014-2019

The Mishimoto Baffled Oil Catch Can for the Ford Fiesta ST is engineered to reduce carbon build-up, a common issue in direct‑injection engines. Extensive road testing on our development vehicle confirmed that the most effective configuration places the catch can within the vacuum‑assisted PCV system. Under both normal and aggressive driving, this location yields the highest level of oil‑vapor accumulation, while the crankcase vent system produces minimal collection on stock or lightly modified vehicles. For the vast majority of Fiesta ST applications, a single catch can installed in the PCV circuit provides optimal performance.

This kit utilizes the Mishimoto 2‑Port Compact Baffled Oil Catch Can, featuring a bronze filter and internal baffle to separate oil from crankcase vapors. Two direct‑fit hoses with pre‑assembled quick‑disconnect fittings ensure straightforward installation, and a dedicated mounting bracket positions the can in a convenient, serviceable location. CNC‑machined aluminium barb fittings provide secure hose connections. As with all Mishimoto components, this catch‑can system is backed by the Mishimoto Lifetime Warranty.

Unlike heated air‑oil separators, Mishimoto catch cans allow blow‑by vapors to fully condense inside the can, including low‑octane oil mist and contaminated fuel vapors. Rather than returning this mixture to the oil pan, the system traps it permanently, preventing harmful deposits from re‑entering the engine.
