Catalog fitment covers the listed 2015-2017 Ford Mustang applications. Exact year and submodel combinations appear in the fitment table below; compatibility must not be inferred for every trim across the full range.

ROUSH's newly-designed cold air intake for the 2015-2017 2.3L I4 Ecoboost engine brings staggering performance increases that can be achieved with an installation that takes under an hour with no calibration required! The ROUSH EcoBoost Cold Air Intake replaces the restrictive stock air intake, unlocking latent power. There's no need for a custom tune, as this CAI system was engineered and designed to work with the completely stock 2.3L I4 engine! 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 RWHP and 27 ft-lbs. RTWQ! Our kit is 74% less restrictive than the stock system at peak HP. Best of all, this system will not void your factory warranty! The filter is washable, re-usable and requires no oiling. The kit utilizes all factory emissions and vacuum lines. Factory mounting locations and hardware are utilized to allow for quick and easy installation.

Use manufacturer part number 421827 to identify this exact Roush configuration. Match the full part number, vehicle application, position, dimensions, material, finish, and included components before ordering.

No Robots. Just Car People.

Buying parts for your Mustang or F-150 should not feel like homework. Too many stores bury you in a giant catalog, slap the same distributor description on every product, and leave you guessing whether it even fits.


We do it the other way. We carry the brands you already trust, we tell you what a part actually does, and we give you the truth about the tradeoffs before you spend a dollar. Drone on that exhaust. Ride quality on those springs. Whether you need a tune. The stuff the big catalogs leave out.
