The K&N 63-2589 Air Intake fits some Ford Mustang models. See vehicle applications link for details.
The K&N 63-2589 AirCharger air intake system replaces the restrictive factory air filter and air intake housing on some Ford Mustang 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 63-2589 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 crank case vent hose and air inlet temperature sensor as well as the blow off valve. 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 an Allen wrench. This air intake cannot be sold in California. It is not legal for use in California or other states adopting California emission standards.

Bought this for my husband for his birthday. His new Ecoboost Mustang was quick from the dealer. Well let me tell you one thing... this Mustang is a rocket. My husband promised no tickets but I don't see how he can avoid it with the K&N CAI installed. You can hear the turbo pulling air and the car is a rocket. Thanks K&N for putting a big smile on my husband's 57 year old face. PS he told me this will help his gas mileage. I hope so he drives 75 miles each way to work.

My K&N made a difference, you can hear the added air flow and the car feels like it is more responsive. Waiting to see if my fuel economy increases, but the car is new so it hasn't even broken in yet. Installation was simple and took about 2 hours, not bad for a non mechanic. Very happy with my selection of the K&N Performance Intake kit.
