Description
The Mishimoto MMINT-FIST-14KPSL is a direct-fit forced induction intercooler engineered specifically for the 2014-2016 Ford Fiesta ST. After running through multiple prototype designs, Mishimoto’s engineers settled on a tube-and-fin core that’s 51 percent larger than the factory unit while still fitting in the stock location, and during testing it dropped intake air temperatures by a full 26°F.
As a dedicated forced induction upgrade for the Fiesta ST’s induction system, this kit doesn’t stop at the core. It replaces both the hot side and cold side intercooler pipes and couplers, giving your force induction setup a complete cold-side refresh in a single package. The larger core delivers a 25-percent increase in internal core volume and a 226-percent increase in external fin surface area, all while keeping the stock mounting location clear so airflow to the radiator and A/C condenser isn’t blocked. Included air diversion plates channel air through the core for maximum efficiency, and the cold-side pipe adds a CNC-machined sensor flange for the stock pressure sensor, a port for meth injection or a boost gauge, plus a silicone hose and CNC plug for deleting the stock sound symposer system — all wrapped in durable silicone couplers and stainless steel T-bolt clamps built to hold under full boost.
Vehicle Applications
This is a specific-fit intercooler kit, not a universal piece — it’s built exclusively for the 2014-2016 Ford Fiesta ST fitted with the 1.6L Ecoboost engine (chassis code B3). It’s also designed to work alongside the Mishimoto Fiesta ST Direct Fit Oil Cooler Kit and is compatible with stock, Mishimoto, or most aftermarket intercooler pipe kits, giving Fiesta ST owners flexibility as they build out their setup.
