MISHIMOTO Ford Focus RS Cold-Side Intercooler Pipe Kit, 2016-2018

The Mishimoto Cold‑Side Intercooler Hose increases airflow to the 2.3L EcoBoost engine in the 2016–2018 Ford Focus RS. This design provides a 40‑percent increase in internal volume over the factory hose and delivers a 46‑percent reduction in pressure drop, improving charged‑air efficiency under elevated boost. The hose is flexible enough to simplify installation yet reinforced to withstand the same high‑boost abuse as an aluminum counterpart.

Constructed from five‑ply silicone and strengthened with internal steel wire, the hose maintains its shape under vacuum and resists deformation during aggressive driving. The one‑piece configuration eliminates the need for multiple couplers, reducing potential failure points and minimizing the risk of boost leaks. Stainless‑steel T‑bolt clamps are included, and installation can be completed in under 30 minutes. Available in black and backed by the Mishimoto Lifetime Warranty, this hose is a durable, direct‑fit upgrade for the Focus RS.
