1999-2004 Mustang GT Throttle Bodies & Plenums

The factory throttle body body performs its basic function admirably, but it's not the most efficient or largest-diameter thing in the whole wide world. Replacing the stock throttle body and intake plenum on your 1999 to 2004 2V 4.6L Mustang GT is one of the easiest ways to get some extra horsepower, torque, and throttle response out of your Pony's 4.6L V8 engine. All of our throttle bodies, throttle plenums, and throttle-plenum kits come from premium manufacturers like BBK Performance to give you extra performance that you can really count on. These kits can be used in conjunction with a wide variety of 99-04 Mustang cold air intakes and other performance upgrades.
