Mishimoto's Fiesta ST induction hose is more durable and will outlast the stock components substantially. To promote improved airflow, this hose has been designed with a smooth internal surface, unlike the accordion-style bends in stock hoses. This particular kit includes a silicone PCV adapter to allow perfect fitment on the 2016+ model Fiesta ST. Whether you are entering your Fiesta ST in the local autocross, or lapping at your next track day, trust Mishimoto and our line of parts to keep your Fiesta ST cool. The Mishimoto 2016+ Fiesta ST Silicone Induction Hose Kit is available in black, blue, or red to match your styling preference. This kit, like our entire line of Fiesta ST performance parts, includes the signature Mishimoto Lifetime Warranty.
