Ford Performance Parts 4.6L 2V PI Intake Manifolds

Replace your broken or cracked intake manifold with an updated 1999-2004 Mustang GT 4.6L 2V PI intake from Ford Performance! The factory GT intake manifold had a plastic coolant crossover that eventually cracked over time, causing increased heat and wear to your engine. Ford Performance has now updated this intake manifold with a new runner design and tooling used to bring back a PI intake manifold. One of the largest improvements was to update the gaskets on the intake to more modern integrated O-ring seals for an easy installation without extra gaskets needed. Another major improvement was the change to an all-aluminum coolant crossover with two sensor bungs, which works with multiple applications. All mounting locations are reinforced and have metal threaded inserts for the fuel rail, coil packs, and lower intake plenum, compared to threading into plastic like other aftermarket options. Ford Performance also includes a new 195 degrees thermostat, thermostat gasket, and alternator bracket.
