The Foust Edition COBB Front Mount Intercooler (FMIC) for your Focus ST 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 57% larger core with streamlined piping, your Focus ST will come alive with charge air that is up to 100 DEGREES COOLER. After removing the grill shutters and drilling 2 simple holes, this FMIC requires no other modification for an easy installation with the included custom silicone adapters. Off the shelf maps are available for the Ford Focus ST Accessport so it's tuned right out of the box!!
