Description
The Mishimoto Oil Cooler Kit (MMOC-FIST-14T) is purpose-built for the 2014-2016 Ford Fiesta ST’s turbocharged 1.6L EcoBoost engine, replacing the factory liquid-to-liquid oil cooler with a dedicated 19-row bar-and-plate cooler mounted up front where it gets maximum airflow. Mishimoto engineers recorded oil temperature drops of over 35°F (19.5°C) using the non-thermostatic sandwich plate, proof that this cooling setup was designed for real track abuse and aggressive street driving, not just showroom looks.
Turbocharged four-cylinder engines like the Fiesta ST’s run hot fast, and hard laps or aggressive tunes can push oil temperatures well beyond what the stock liquid-to-liquid cooler can manage, accelerating engine wear over time. This Mishimoto oil cooler kit bypasses that stock unit entirely using a new CNC center bolt and an aluminum coolant bypass tube, so oil is routed straight through the larger external core instead of sharing duty with the coolant system. Application-specific braided stainless steel lines with -10AN fittings move oil between the engine and cooler with minimal pressure drop, and the kit is engineered to keep the cooler’s location clear of aftermarket air intakes while remaining compatible with stock and most aftermarket intercooler kits. Whether you’re chasing consistent lap times or just want more margin against heat soak on spirited street drives, this Mishimoto cooling upgrade is built to handle it.
Vehicle Applications
This Mishimoto oil cooler kit is a direct-fit application for the 2014-2016 Ford Fiesta ST, built on the B-car platform and powered by the 1.6L EcoBoost engine. Application-specific mounting brackets and a spacer are included so the cooler and lines install using the factory mounting points without additional fabrication.
