The K&N 63-2565 Air Intake fits some Ford Mustang GT models. See vehicle applications link for details.
The K&N AirCharger 63-2565 air intake system replaces the restrictive factory air filter and air intake housing in some Ford Mustang models. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your Mustang’s 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 63-2565 air intake comes with a chrome topped K&N high-flow air filter and a heat shield that installs into the previous air box space. This allows cooler, denser air to be directed through a custom molded intake tube into the engine’s throttle body for a guaranteed power gain. The oversized 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 requiring only a screwdriver, socket set, pliers 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.

Outstanding product. Makes my 2009 Mustang GT sound better and have noticed the throttle response is improved. Haven't got the chance to really get into it and test it out at wide open throttle or take it to the red line yet? But I really like the product and recommend it to everyone out there. Thanks K&N

Couldn't be happier with this purchase! Was the best $300 I've spent in a long time. Was easy to install and now my 2008 Mustang sounds even better than it did before. Seems to me that it shifts smoother and definitely gave my car more power in every gear. Also noticed that at higher mph the rpm's don't go nearly as high as they did, so therefore better gas mileage. Thank you K&N:)) You have a great product!

I own 2 vehicles and have put K&N performance intake systems on both. Not only has the performance of the car and truck both improved but the ease of cleaning and renewing the filters is a breeze and they have paid for themselves many times over. The latest intake kit I put on my 2007 Mustang GT and could feel the difference as soon as I started it. It simply is a great product. Thanks.
