Description The COBB Fiesta ST Intercooler Upgrade is the easiest way to drastically improve power when coupled with tuning from the Accessport. Even when stock, the factory FMIC can be overwhelmed with heatsoak. By using a 55% larger core, your Fiesta ST will come alive with the new found colder charge air. This upgrade requires no modification to the car for an easy installation with the included custom silicone adapters. Factory-like fitment for the 2014 Fiesta ST.
