Ford Performance Intake Manifold 4.6L 2V SOHC 2001-2004 Mustang GT M-9424-P46A

If you're running a 2001-2004 Mustang GT with a 4.6L SOHC 2V engine, the factory intake manifold is holding back your potential. The Ford Performance M-9424-P46A replaces that restrictive casting with optimized runner geometry and a deeper plenum, delivering measurable gains in throttle response and peak power. This is the bolt-on upgrade that serious GT owners choose when they're ready to unlock what their engine can actually do.

Engineered with all-new tooling, the manifold features a larger bell mouth and shorter, more rounded runners that reduce turbulence and improve charge density. The composite construction with a reinforced metal crossover resists cracking under sustained heat cycles—critical for track use. Installation is straightforward on 1999-2004 PI heads, and the kit includes everything you need: the manifold, alternator bracket, thermostat housing, gaskets, and hardware.
