without having read the entire thread i will chime in with "changing the plugs on the duratec is cake"...and im an automotive dope pretty much
many say you dont even have to remove the coil pack to get to the rear bank of plugs but i did have to remove it....however, first time it took me an hour to do it and since then its like a pitstop...goes really quickly
only plugs i'd use would be motorcraft and yeh i paid 10 bucks a pop from the mis-dealer too
