How To Install Mustang GT Steeda ProFlow Cold Air Intake (15-17)
If you are looking to bolt on more horsepower and torque to your Coyote Motor, this 2015-2017 Mustang GT Steeda ProFlow cold air intake is just what you need!The high velocity cold air intake allows your engine to bring in more air, which frees up more power! Steeda offers two different versions of this cold air intake. With part number ST-5553194, the cold air intake requires a tune. With part number ST-5553193, the cold air intake does not require a tune. Be sure to pick the correct one, because installing the one that requires a tune could cause engine issues if you do not use a tune on your S550.
That being said, with the addition of a tune, Steeda saw an improvement of 30rwhp and 23 ft/lb of torque from the ProFlow intake!
