Description
The Mishimoto MMINT-FIST-14KBSL is the production result of a multi-prototype development program built specifically for the Ford Fiesta ST: a tube-and-fin forced induction intercooler with a core 51-percent larger than the factory unit, engineered to drop intake air temperatures by a measured 26°F (15°C) during testing. Every Fiesta ST owner chasing a cooler, denser charge will recognize this as a purpose-built forced induction upgrade rather than a generic bolt-on.
This forced induction system replaces both the stock intercooler and its hot-side and cold-side piping in one kit, pairing a 25-percent increase in internal core volume with a 226-percent jump in external fin surface area for improved heat rejection without adding bulk. The all-aluminum, TIG-welded core keeps the stock mounting location so airflow to the radiator and A/C condenser is not blocked, while tube-and-fin construction trims weight compared to a bar-and-plate design. Included air diversion plates channel incoming air directly through the core for maximum efficiency, making this Mishimoto induction upgrade a genuinely integrated forced induction solution rather than a single swapped part.
Vehicle Applications
This intercooler kit is a specific fit for the 2014-2016 Ford Fiesta ST equipped with the 1.6L Ecoboost engine (chassis code B3). It is not designed as a universal part and is engineered around this exact platform’s engine bay and airflow path.
