Many prototypes entered, but only one came out on top. The engineers went through multiple different designs for this Fiesta ST intercooler, weighing the benefits and downfalls of each. The final design consists of a tube-and-fin style intercooler in order to allow airflow to the radiator and reduce overall weight. The core size is 51% larger than stock, and also provides a 25% increase in internal core volume. During testing, this Fiesta ST intercooler dropped intake temperatures by a huge 26 F! This Fiesta ST intercooler kit includes air diversion plates to channel air through the cooler for maximum efficiency. The Mishimoto Fiesta ST cold-side intercooler pipe features a CNC-machined sensor flange for the stock pressure sensor, a port for meth injection or a boost gauge, and a silicone hose and CNC plug to allow deletion of the stock sound symposer system. Mishimoto's Fiesta ST intercooler piping features durable silicone couplers and stainless steel T-bolt clamps for reliable holding power when you're hitting full boost on a long straight. The all-aluminum, TIG-welded construction is of the highest quality, and like all Mishimoto Fiesta ST parts, it is backed by the Mishimoto Lifetime Warranty!
