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.

Awesome product. Installed on a 5.0 Coyote V8 in a 2016 Mustang GT. Yes, it makes a difference. Fit perfect.

This was my second purchase of the K&N FIPK... My first installation was on my 2000 Mustang GT... I was very satisfied with the performance and sound of authority when it spoke... This installation on my 2017 Mustang GT went a little easier; because, I was experienced with the little tricks you learn working with them... I was pleasantly surprised that this installation delivered more performance and those exhaust and intake sounds that tell people, I'm not quite stock... Not loud; but that rumble us gearheads like...

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

I love the product I did though have an issue with the install. What surprises me is the K&N Customer service is closed on Saturdays. It seems many people would buy a kit like this and choose a fine Saturday to install it. They should consider opening a customer service capability on the weekend. My problem though is that this kit was designed for a 2015 Mustang and mine is a new 2016. It ALMOST worked perfect. The mounting bracket under the main heat shield was too high. I was able to modify it by cutting a slot above the factory hole and made it work fine. K&N should consider sending both brackets and this kit would work well for either year. Other than that all the other parts went in fine, sounds great, and truly seems like it has a little more pep. It had 435 to start (sticker engine rating) so any extra is just a boost. Looking forward to years of great use.

Installed this in my 2015 Mustang GT yesterday. It was extremely simple & the results from the sound diff. to the performance are awesome & no tune needed. Best inexpensive mod. I could make. Still going to do high perf. tune, etc. etc. etc. I am a motor head.
