2003 Expedition 5.4L
I don't actually have an answer for you.
I did do a Ford plant tour down in Norfolk VA. (F150 Online/ Performance Products rally). I saw the '03 motors waiting to be installed. I can say that the 4.6's looked slightly different from my '98. The 5.4's also looked different. It looks like they have made some changes to the intake plenum (among other things).
I guess I would say don't assume that they would be the same.
