MISHIMOTO Ford Fiesta ST Intercooler, 2014-2019

Mishimoto engineers evaluated multiple prototype configurations to determine the most effective intercooler design for the 2014–2017 Ford Fiesta ST. After extensive testing, the final selection utilizes a tube‑and‑fin core to maintain airflow to the radiator and reduce overall weight. The upgraded core delivers a 51‑percent increase in external size and a 25‑percent increase in internal volume compared to the factory intercooler. During controlled testing, this intercooler reduced intake temperatures by 26°F, providing consistent performance under sustained boost.

This intercooler is a direct‑fit upgrade and is fully compatible with both the stock intercooler piping and Mishimoto’s 2014–2017 Fiesta ST Intercooler Pipe Kits. When paired together, the system forms a complete high‑performance charged‑air package. Air‑diversion plates are included to channel airflow through the core for maximum cooling efficiency. The assembly is constructed from TIG‑welded aluminum for long‑term durability and reliable performance. As with all Mishimoto Fiesta ST components, this intercooler kit is backed by the Mishimoto Lifetime Warranty.
