The K&N 63-2590 Air Intake fits some Ford Mustang GT models. See vehicle applications link for details.
The K&N 63-2590 AirCharger air intake system replaces the restrictive factory air filter and air intake housing on some Ford Mustang GT models. K&N air intakes are designed to dramatically reduce air intake restriction as well as smooth and straighten air flow. This allows your engine to inhale a larger amount of air than the factory air filter assembly. More air means more usable power and acceleration throughout the engine’s RPM range. The 63-2590 air intake comes with a chrome topped K&N high-flow air filter and a heat shield that installs into the original air box space. Air is directed through an aerodynamically engineered intake tube into the engine’s throttle body for a guaranteed power gain. The tube accommodates the factory mass air sensor, idle bypass hose, EVAP vent hose and crank case vent hose. The oversized cone shaped air filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions. This air intake is relatively easy to install, usually in 90 minutes or less using your vehicle’s existing factory mounting points. The tools needed are a screwdriver, ratchet set and several wrenches. This air intake cannot be sold in California. It is not legal for use in California or other states adopting California emission standards.

I put this on my wife's 2015 Mustang GT. First thing I noticed was the sound and it wasn't what I was expecting. Everything I read said it would improve the sound and that it would have a deaper, more growly tone but it actually made the Mustang quieter. HUGE disappointment on the sound. However, it did give it more power and that's a HUGE plus. It does have (Brand Names) on it so now we're off to the shop to hopefully get some growl back

Good fit and good sound. Didn't notice much as far as MPG or pull, but I love the induction sound.
