Product Description

The Roush 422087 Cold Air Intake Kit is a performance-enhancing induction upgrade designed specifically for 2018-2023 Ford Mustang models equipped with the 2.3L EcoBoost turbo four-cylinder engine. This cold air system replaces the restrictive factory intake with an engineered intake tube, larger airbox, and high-flow dry filter that helps deliver cooler and denser air to the turbocharger. Better airflow improves throttle response and overall engine efficiency without the need for a calibration or custom tune, making this a simple and effective upgrade.

Installation is straightforward and typically completed in about an hour using existing factory mounting points and included hardware. The dry, washable, and reusable filter eliminates the need for oiling while supporting long-term maintenance. Emissions legality across all 50 states applies to 2018-2021 models, providing broad legal coverage for street-driven vehicles. The Roush 422087 intake offers improved engine sound, throttle response, and airflow compared to the stock intake, making it a popular choice for Mustang EcoBoost owners looking for a reliable, bolt-on performance upgrade.
