I live in the UK so getting parts is a fairly big deal. What is the correct term for the coil packs that sit on the spark plugs as I think I need to replace these and am having trouble sourcing the part. Am really glad I joined the forum now.

Coil packs... They are about $30 a piece, and rarely fail. Pull one of your plugs and check them. The copper champions only last about 30k miles in these engines, but they're the plugs you want. The 4.7L doesn't much like platinum or iridium plugs unless you are running a lot of timing advance like in the HO version of the engine.
