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.

K&N 63-2565 Air Intake Product Reviews

My son bought this for his 2014 Ford F150 with 5.0 V8. The increase in throttle response and the obvious horsepower increase is incredible. He is checking the gas mileage now, but it's so fast it's hard to keep your foot out of it. This was relatively inexpensive for the major performance improvement. Highly recommend.

I have experienced the same positives that others have said. I have a 2009 CS/GT that sounds even better now and definitely has more juice to it when I accelerate. I can feel the increased torque and horse power for a quicker Mustang. Actually it has made my Mustang more fun to drive. I am very pleased with my K&N cold intake filter. I should also add that it was cheaper by $50.00 ordering it on line than getting it through my Ford dealership. Not being mechanically inclined the dealership was reasonable in charging me to have it installed.

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
