Description
The Mishimoto Focus ST Performance Air Intake (MMAI-FOST-13P) is a direct-fit cold air intake engineered specifically for the 2.0L EcoBoost-powered Ford Focus ST, built around an aluminum intake pipe finished in polished silver and paired with a black powder-coated airbox. Dyno-proven to add up to 6 whp and 5 wtq on the stock tune, this Mishimoto intake installs without any tuning while giving the Focus ST a noticeably more aggressive intake tone under acceleration.
As a purpose-built air intake system, this kit is designed to move more air with less heat soak than the factory setup — which is the core job of any cold air intake: pull cooler, denser air into the engine for a cleaner, more responsive feel. The high-flow oiled air filter is positioned to receive maximum airflow from the front of the vehicle, while the black powder-coated airbox and stock cool air duct routing work together to shield the filter from underhood heat. Whether you’re cross-shopping this cold air intake against a k&n cold air intake, an afe cold air intake, or an injen cold air intake, the Mishimoto kit arrives as a complete, direct-fit air intake filter solution rather than a filter-only upgrade, and it’s backed by the Mishimoto Lifetime Warranty.
Vehicle Applications
