Product Description

The Mishimoto MMAI-FOST-13P Performance Air Intake Kit is a direct-fit upgrade engineered specifically for 2013-2018 Ford Focus ST vehicles equipped with the 2.0L EcoBoost I4 engine. By replacing the restrictive factory intake components with mandrel-bent aluminum piping and a high-flow oiled performance filter, this intake improves airflow and throttle response while delivering a more aggressive induction sound during acceleration. The large airbox design helps isolate the filter from hot engine bay air, promoting cooler, denser airflow to the turbocharger.

Designed for ease of installation, the intake retains the factory mass airflow sensor using a CNC-machined housing, eliminating the need for ECU tuning on stock engine management. With durable construction and enhanced airflow efficiency, this intake provides a balanced performance improvement backed by Mishimoto's lifetime warranty for long-term reliability and enjoyment.
