When it comes to adding easy bolt-on modifications to your new S550, choosing a quality cold air intake is a smart investment. But enthusiasts are often faced with the challenge of finding a kit that will not only add usable power but will work in sync with their personal build needs.
Steeda’s S550 ProFlow Cold Air Intake is a great choice for 2015+ Coyote-powered Mustangs with the stock intake manifold. The cold air intake is available for 2015-2019 Ford Mustang GT’s and will allow your Coyote’s induction system to breathe much more freely than the stock intake system.
