Your 2003 GT has PI heads unless someone has swapped in a non-PI motor.
It may have a Dorman PI intake.
The part numbers on the plastic
the bolts that hold the COP into the intake go DIRECTLY into the plastic and resemble wood screws. A real Ford unit will have brass inserts and real machine screws.
The Dorman unit will have two ECT bosses on the metal coolant cross over.
Just FYI, these are both NPI intakes; they reversed the runner order when moving to PI (starts with Cyl # 5 instead of Cyl # 1). Some NPI cars got the aluminum crossovers (my 98 had one).
