Mishimoto MMAI-RS-16WBK Performance Cold Air Intake Kit for 2016-2018 Ford Focus RS

The Mishimoto MMAI-RS-16WBK Performance Cold Air Intake Kit is engineered specifically for the 2016-2018 Ford Focus RS to improve airflow, throttle response, and overall engine performance. This complete intake system replaces the factory airbox and intake pipe with a high-flow design that routes air efficiently to the turbocharger. Its 3-inch aluminum intake pipe and precision-fit mounting hardware provide reliable installation without cutting, drilling, or modifying factory components.
The enclosed airbox maintains a design similar to the original system while improving pressure drop through an open-top configuration that exposes the filter to additional airflow. The airbox seals against the hood and uses the factory air inlet ducts to draw cooler air from the front of the vehicle. Weather stripping around the inlet ports helps maintain a secure, sealed fit, supporting consistent performance in daily driving and demanding conditions. The included high-flow air filter is positioned to receive maximum available airflow while providing effective engine protection.
Extensive road testing and dyno testing demonstrated maximum gains of up to 12 wheel horsepower and 15 wheel-pounds of torque on a stock tune. The system is designed to operate with the factory calibration, so no additional tuning is required. As a direct bolt-in upgrade, the Mishimoto intake is compatible with 2016, 2017, and 2018 Ford Focus RS models and is backed by the Mishimoto Lifetime Warranty. This product is EPA compliant and carries California Air Resources Board Executive Order D-759-2.
