Increase the airflow to your 1.6L EcoBoost with the Mishimoto Fiesta ST cold-side intercooler pipe kit for the 2014-2019 Ford Fiesta ST. The stock cold-side Fiesta ST intercooler pipe is riddled with restrictive bends and small diameter sections that impede airflow. These Mishimoto intercooler pipes have a 2.5in diameter and are mandrel-bent to eliminate any restrictions. When you're turning up the boost on your Fiesta, these pipes will have no problem supporting the power you throw at them. Plastic is always a material Mishimoto'strives to eliminate, and the stock cold-side Fiesta ST intercooler pipe is unacceptable. The stock pipe is constructed completely of weak plastic that is bound to leak over time. The Mishimoto cold-side intercooler pipe is comprised entirely of lightweight aluminum and 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 cold-side Fiesta ST intercooler piping features durable silicone couplers and stainless steel T-bolt clamps to ensure leak free connections. Installation can completed in under 30 minutes with no modifications to the engine bay, as these cold-side Fiesta ST intercooler pipes are a direct fit and work with both the stock and Mishimoto performance Fiesta ST intercoolers. Mishimoto's Fiesta ST cold-side intercooler piping is available in either a polished or wrinkle black finish, and, like all of our Fiesta ST performance parts, includes the Mishimoto Lifetime Warranty.
