i know if you have the 5.4L V8 you will have coil packs. not spark plugs
COP system Coil on Plug. Coils are located on the top of the spark plugs
The plugs and coil packs are located on top of the engine. If you look at the fuel rails ( they are silver in color ) which will be on both sides of the throttle body the small coil packs are located under them. Use caution when R&R the plugs and packs not to break the clips holding them and damage the fuel rails.
They are on top of the cylinder head below the coil packs. If you are replacing them it will be BEST to use Motorcraft plugs and to put anti-seize on the threads.
