Ported 99 upper intake on 03 plenum

Will an intake from a 1999 gt fit an 03? How did the 99s flow compared to the 03?

I think they are the same, there are only very small differences, most of them are cosmetic like hood scoops, and fancier radio....

They have a different PCV inlet size, but you can work around that with a couple pieces of hose, a couple clamps and maybe a plastic adapter tube...Ck the difference and you'll see what I mean, then head to the auto parts store and check out there hoses, clamps, etc...

I have ported uppers for people and any upper plenum will bolt up from any 2v (other than bullit or SVO) the only issues are as stated above, you may need to modify some of the hoses.
