Turbocharged 1.6L EcoBoost engines like the Fiesta ST's can spike oil temperatures within a few laps or during hard street driving. This Mishimoto kit adds a large 19-row oil cooler mounted at the front of the vehicle for maximum airflow, bypassing the restrictive factory liquid-to-liquid unit for a bigger temperature drop. Application-specific braided stainless steel lines with -10AN fittings route oil between the cooler and engine, while the thermostatic sandwich plate holds oil in the block until it reaches operating temperature before opening flow to the cooler. The Stealth Black cooler is backed by the Mishimoto Lifetime Warranty.
