THere are 8 coils and plugs. THey are located on top of the engine, in rows of 4 (one row on each side), in the middle of each valve cover, under a metal plate. Remove the plate on each valve cover, and you will see the coils each with an electrical connector and held down with a 7mm screw. Remove the coils and down in each hole (about 3 inches down) is the plug, one under each coil.
Good question.
A Lincoln Navigator has the Coil On Plug ( C.O.P.) ignition system with ( 8 ) individual coils firewall 4 - 8 3 - 7 2 - 6 1 - 5 front of Lincoln Navigator
On a Lincoln Navigator : firewall 4 - 8 3 - 7 2 - 6 1 - 5 front of vehicle
8 -one per cylinder
On a 2004 Lincoln Navigator : firewall 4 - 8 3 - 7 2 - 6 1 - 5 front of vehicle
The spark plugs are located beneath the individual ingnition coils. Remove each coil then remove spark plug as normal
The Ignition Coil is the one that cause misfire or Spark Plugs

The firing order is ( 1 - 3 - 7 - 2 - 6 - 5 - 4 - 8 ) It has the Coil On Plug ( C.O.P. ) ignition system The engine cylinder locations are numbered : firewall 4 - 8 3 - 7 2 - 6 1 - 5 front of Lincoln Navigator
On a 2003 Lincoln Navigator : It has the Coil On Plug ( C.O.P. ) ignition system with ( 8 ) individual coils firewall 4 - 8 3 - 7 2 - 6 1 - 5 front of vehicle
Your truck does not have ignition coil. Instead, it has coil packs. The 5.4L has eight coil packs one on each spark plug. The 4.6L has two coil pack blocks 4 on each block.
