Will the other one perform better or last longer? They look about the same.A: This Replacement PI Intake Manifold w/ Gasket Set is an aftermarket replacement for your factory intake manifold for the 1999 to 2004 Mustang GT. The Ford Racing Intake Manifold will be slightly larger and flow better than this factory replacement.Q: This replacement intake has the pre installed gaskets right? Will I need to buy the gasket strip separately and place under the manifold? Or do I just clean it off and set the manifold directly on the metal? Will the pre installed gaskets prevent leaks or do I need a separate gasket strip?A: Yes just set the new intake with the pre installed gaskets directly on the heads after cleaning first of course, the gaskets provided should comply with the oem specifications therefore they should give no problemQ: What are PI(Performance Improved) heads, and how do you know which ones I have? My car is an 01GT w/ factory heads.A: PI heads are what Ford called the Performance Improved cylinder heads on the 99-04 4.6L 2v Modular V8. Short version: You have PI heads, while stock 96-98 GT models don't. Long version: The 96-98 SN-95 Mustang GT models used a very similar 4.6L 2v Modular V8, but they only made 215-225 HP stock. With the release of the New Edge models, Ford swapped out the heads for the PI ones, made this better intake manifold to fit them, and swapped out the camshafts for better ones. This brought the engine to 260 HP for 99-04. Outside of these part swaps, the non-PI engines are functionally the same as the PI engines.Q: Is this a dorman brand?A: The brand is OPRQ: What alternator bracket do I need? I have the 2000 Mustand GT. Do I just simply order a alternator bracket off a 2001 Mustang GT?A: I ordered the manifold, and put it on a 2000 GT I ended up not needing the bracket. I also read for the people who need the bracket you can just drill new holes in old bracket.
