ROUSH's newly-designed cold air intake for the 2015-2017 2.3L I4 Eco boost engine brings staggering performance increases that can be achieved with an installation that takes under an hour with no calibration required! The ROUSH Eco Boost Cold Air Intake 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, tested, and designed to work with the completely stock 2.3L I4 engine! Paired with Ford's innovative Eco Boost engine, our ROUSH Cold Air Kit feeds cooler, denser air to the Turbo, increasing potential power output by up to 29 RWHP and 27 ft.-lbs. RTWQ! Our kit is 74% less restrictive than the stock system at peak horsepower. Best of all, this system will not void your factory warranty.
