Re: spark plugs
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.
