Product Description

The Roush 421828 Cold Air Intake Kit is an engineered performance induction upgrade for 2015-2017 Ford Mustang models equipped with the 3.7L V6 engine. Designed to replace the restrictive factory intake, this kit features a dry, washable filter and optimized intake tube to reduce intake restriction by approximately 20 % over stock systems. This improved airflow helps increase throttle response and unlock around 10.5 additional horsepower and 9 lb-ft of torque without requiring custom tuning or calibration.

Installation is straightforward and utilizes existing factory mounting points, emissions connections, and vacuum lines - meaning no aftermarket modifications are needed. The dry, reusable performance filter simplifies maintenance: just wash and dry when service is required. Emissions compliance across all 50 states for the years 2015 to 2017 adds peace of mind for street-driven Mustangs. This intake delivers enhanced engine breathing, improved driving responsiveness, and elevated under-hood aesthetics with ROUSH branding.
