Increase the airflow to your 1.6L EcoBoost with the Mishimoto hot - side Fiesta ST intercooler pipe kit for the 2014 - 2019 Ford Fiesta ST. The stock hot - 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. These hot - side Fiesta ST intercooler pipes feature durable silicone couplers and stainless steel T - bolt clamps to insure leak free connections. Installation can completed in under 30 minutes with no modifications to the engine bay, as Mishimoto's Fiesta ST intercooler piping is a direct fit and works with both the stock and Mishimoto performance Fiesta ST intercooler. The Mishimoto Fiesta ST hot - side intercooler pipe kit is available in either a polished or wrinkle black finish and, like all of our Fiesta ST parts, includes the Mishimoto Lifetime Warranty.
