There are no plug wires on a 5.4. No distributor either. It's all done via the computer and the crankshaft position sensor.

The plugs are below the coil packs in the top of the cylinder head. Just remove the small bolt holding each coil in place, unplug the electrical connection at each coil, pull the coil up and out, and remove the spark plug with the right socket. When removing the electrical connections, be sure to label them so you don't get them mixed up. It's tough to reconnect them wrong, but it is possible.

Do the spark plugs need to be replace on 5.4's? If yes, what mileage?

most of the plugs used in todays vehicles are platinum tipped and are supposed to be good for 100,000 miles but i prefer new plugs at around 60,000 to 70,000 unless they arent wearing down.
the best thing to do is pull a couple of them and see if the electrode is eroded and make your decision based on what you find.
