Like most engines, the 4.0L V6 under the hood of your 2005 to 2009 Mustang runs pretty rich from the factory and increasing airflow should be one of your top priorities when trying to add horsepower and torque. Our selection of Mustang V6 cold air intakes, throttle bodies, and throttle body spacers are capable of adding 10 to 20 horsepower to your Pony's output, depending on your specific part combination. Combining some custom tuning with any of these parts can get you even more power and make your V6 Mustang an absolute blast to drive. Once you're done with these basic power-adders, take a look at our ignition upgrades, exhaust kits, or powerful superchargers for even better performance gains.
