Just like basically every car that has come before it, the factory intake system of the 2005 to 2009 Mustang GT is not exactly the most efficient or powerful part of your Pony. The good news is that there a ton of bolt-on intake kits to replace the thing. While many of our 2005-09 3V cold air intake kits can be bolted right on to your Pony, more powerful kits require custom tuning in order to function properly and get you maximum performance. To get even better performance out of your Mustang, take a look at our tuners and intake packages.
