in a pre-08 4.7 they are easy. especially if you have a cold air intake and already removed the resonator box.
remove the harness to the coil, take the 10mm nut off and pull the coil straight up. then drop a spark plug socket ona long extension..
changed the plugs in my dad's truck last weekend, it didn't even take an hour.
