The all-new 2015 Mustang 2.3L ROUSH EcoBoost Cold Air Kit replaces the restrictive stock air intake, unlocking latent power and fuel efficiency. There’s no need for calibration or a custom tune as this CAI system was engineered and tested to ensure that no calibration changes are required. Paired with Ford’s innovative EcoBoost engine, our ROUSH Cold Air Kit feeds cooler, denser air to the Turbo, increasing potential power output by up to 29 HP and 27 Lb-ft of torque. Our kit is 74% less restrictive than the stock system at peak horsepower.

An innovative dry filter is composed of two layers of wire mesh for durability and is proven to retain its shape under high airflow. The filter is washable, re-usable and requires no oiling.

Included in the kit is the air filter with clamp, injection-molded lower air box/tray with installed EPDM foam hood seal, Blow Molded clean air tubes, heat extractor foam insert, and all required mounting hardware. The kit utilizes all factory emissions and vacuum lines. Factory mounting locations and hardware are utilized to allow for quick and easy installation.
