Steeda’s Race-Proven Closed Box Intake is Largest on the Market

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.

“With our tune on our chassis dyno, we were able to achieve 25 horsepower at the top end and 30 horsepower down in the midrange,” said Brian Dopp from Steeda Autosports. “That’s going to improve acceleration and throttle response and the way the car accelerates.”

Steeda was able to achieve these numbers thanks to a massive 121 mm inlet tube, which is currently the largest on the market. The closed box design has also gone through extensive testing on stock vehicles as well as the team’s S550 Road Race Car and the popular Steeda “Silver Bullet” Drag Car.

Although the cold air kit does require a tune, Steeda provides all the necessary hardware for a quick and easy install making it a smart choice for Mustang enthusiasts looking to take an otherwise stock Mustang to that next level of performance.

On the company’s website, Steeda also provides an impressive list of tuning software for when you are ready to make the upgrade.
