The ford plug is the same as the autolite plug... For the Duratec, the Autolite you want is the APP764... It is the double plat. plug, but it is worth the difference in price.
I dunno the part number for the Zetec...
EDIT: Some people have had good luck with the FRPP 9mm wires... Others have said they aren't as good as stock for a durability standpoint. Although, they are more than likely my next set of wires...
