For the V6?
Plugs:
Autolite Double Platinum #APP764
(Or motorcraft equiv. same thing..)
gap to 0.054 (not set out of the box, so just do yourself a favor and gap them..
Wires:
Motorcraft OEM replacement wires or (MAYBE) Ford Racing 9mm wires.
Replace on the engine one at a time, so you don't mix them up and reverse the firing order on any (the duratec is NOT a straight up match.. the coilpack and engine aren't identical)
Belts:
gatorback makes a nice one, and not much more than the oem replacement, but is "said" to last longer.. no real world experience with that, though.
