For as long as cars have been around, there have been people trying to make them go faster. Our obsession with horsepower isn’t a new one, but it has never been quite as extreme. With muscle cars for sale from each of Detroit’s automakers with supercar levels of horsepower on tap, the horsepower wars rage on. Ford Performance is no stranger to this battle, and now they are bringing some upgraded firepower with a new Mustang GT Performance Package.
Listed as the Cold Air Kit with Calibration, this new option from Ford Performance offers a 19 horsepower and 42 pound-feet of peak torque increase over the standard 2018-2020 S550 Mustang GT figures. That brings the totals up to 479 horsepower and 442 pound-feet, which falls in line with the movie-inspired Mustang Bullitt models. While the McQueen-derived pony car’s do come with a bit of specific hardware, they also carry a MSRP $10,000 higher than a standard GT. This package listed as part number M-9603-M8B is quite a bargain by comparison, carrying a sticker price of only $1,275. Ford also offers power upgrades for the Ranger via a similar kit.

In order to find those extra ponies inside the 5.0L Coyote V8, the Cold Air Kit with Calibration includes a cold air induction system, a new 87-millimeter throttle body with an adapter plate for fitment, and of course a new engine calibration to make everything play nice. That package can be installed at any Ford dealer, and when installed it will not void any factory warranties. The package is even 50-state legal, though it does require 91 octane to be used for optimal performance.
While the standard Mustang GT is already quite the potent muscle car, nobody is going to be upset that Ford is offering it’s buyers a bit more oomph. While we all patiently await the arrival of the rumored, Bullitt-replacing Mach 1 model, this Mustang GT Performance Package will have to tide over the Blue Oval faithful for now.
