Product Description

The Mishimoto MMAI-RS-16WBL Cold Air Intake Kit is a performance-focused upgrade designed for 2016-2018 Ford Focus RS models equipped with the 2.3-liter EcoBoost I4, AWD configuration. This intake replaces the restrictive factory air intake with mandrel-bent aluminum piping and a high-flow oiled performance filter to increase airflow, improve throttle response, and deliver a more engaging induction sound. The filter and airbox are engineered to capture cool air from the front duct while reducing intake restriction compared to stock components.

Finished in a wrinkle nitrous blue powder-coat for enhanced under-hood aesthetics, the MMAI-RS-16WBL retains the stock mass airflow sensor using a precision CNC-machined housing and installs with a simple bolt-on process that does not require ECU tuning on stock vehicles. The enclosed airbox design helps shield the filter from hot engine bay air, preserving cooler intake temperatures for more consistent performance. Backed by the Mishimoto Lifetime Warranty, this intake offers a balance of style, function, and performance for RS-equipped Focus enthusiasts.
