Description
The Mishimoto MMAI-RS-16WBL is a full replacement cold air intake system engineered specifically for the 2016-2018 Ford Focus RS and its 2.3L EcoBoost engine. Unlike a simple filter swap, this kit replaces every core component of the OEM intake system, including the airbox and intake pipe, with a 3-inch aluminum pipe that routes all the way to the turbo. Mishimoto’s engineers logged hundreds of miles of road testing and countless dyno runs to develop this air intake system, resulting in repeatable, stock-tune-safe gains.
This cold air intake filter setup is built around a redesigned airbox that mirrors the stock airbox’s shape while improving pressure drop through an open top that exposes the filter to more incoming air. The airbox seals against the hood to stay fully enclosed and uses the factory air inlet ducts to pull air from the front of the vehicle, with weather stripping around the ports to prevent movement. The result is an air intake filter positioned to receive maximum airflow, a black powder-coated airbox that keeps unwanted hot air away from the filter, and a noticeably more aggressive intake tone under acceleration—all while working with the stock tune, no additional tuning required.
Vehicle Applications
This intake is a direct bolt-in for the 2016-2018 Ford Focus RS equipped with the 2.3L EcoBoost engine. No cutting or modification to factory components is necessary for installation. The intake carries CARB EO number D-759-2, which currently covers model years 2017-2018.
