The Mishimoto non-thermostatic oil cooler kit for 2013–2018 Ford Focus ST is a direct-fit solution designed to reduce oil temperatures during aggressive driving. The kit uses a large 19-row cooler mounted for maximum airflow, braided stainless lines with -10AN fittings, and a sandwich plate to route oil through the cooler for improved thermal control. Mishimoto testing showed consistent oil temperature reductions versus stock, helping protect turbocharged engines under track or spirited use.
