Mishimoto Hot Side Intercooler Pipe Kit Polished | Ford Focus ST (13-18) (MMICP-FOST-13HP)

The Mishimoto hot-side intercooler pipe kit for the Ford Focus ST is designed to improve charged-air flow on the route to the intercooler. Its revised piping reduces bends and increases the diameter to 2.5 inches, providing 14 percent more volume than the stock pipe. The smoother, larger passage helps reduce airflow restriction and turbulence; the source also reports gains of 8 horsepower and 10 lb-ft of torque. The polished aluminum pipe is paired with durable silicone couplers in place of degradation-prone stock rubber. These couplers use five layers of heat-resistant fibers and wire reinforcement to withstand elevated temperatures. This version features a polished finish, and the kit is covered by Mishimoto’s Lifetime Warranty.

This kit is specified for 2013–2018 Ford Focus ST models. It replaces the factory hot-side intercooler pipe, addressing its bends, restrictive inner diameter, and muffling equipment to improve airflow toward the intercooler. The supplied silicone couplers connect the upgraded pipe and are designed for greater heat durability than the stock rubber couplers. The product description does not specify engine details, chassis code, installation hardware, or whether installation is bolt-on, so confirm those requirements for your vehicle before purchase. It is an airflow upgrade for Focus ST owners seeking the stated performance benefits in street or other driving applications; the source does not identify a particular use case. This listing is the polished-finish version.
