The Roush Cold Air Kit for 2015–2017 Mustang 3.7L V6 replaces the stock intake with a higher-flow system that reduces restriction by about 20% and can produce a noticeable increase—around 10.5 hp and 9 lb-ft of torque—without custom calibration. The dry, washable filter retains shape under high airflow and needs no oiling. The kit uses factory emissions and mounting locations and includes all required hardware for straightforward installation.
