There are access covers (2 of them, one for the left side, on for the right) over the ignition coils. The plugs are under each coil. Be sure to blow and/or wipe dirt, oil or debris from the spark plug wells out BEFORE removing the plugs, or you'll dump that crap straight into the cylinders.
It is located over the cylinder head.
4-cylinders have four spark plugs, 6-cylinders have six spark plugs, 8-cylinders have eight spark plugs, etc, etc, etc

my petrol 04 Grandis is about to have its first set of plugs as part of its 54K service.
the 04 have platinum plugs and they are preset
Have it checked for codes, then you will know the answer.
They are located right in between the where intake manifold ends and the valve cover starts. You must remove a 7mm hex head bolt to remove the coil unit, then unplug the wire for the coil unit for each spark plug, remove the coil unit and you need a special very long spark plug socket to go down into the spark plug hole. Beware!!! The 4.6 and 5.4 Ford V-8 engines are known to have the spark plugs break off in the head for no appearent reason whatsoever and without warning.
They Are under the Intake manifold like on my 04 kia sedona, You have to removethe center part of the manifold.
you have to remove the coils off of each spark plug, than under the coil is the plug.Remove the plug as any other plug.
Same with the 04 Lincoln nav, by your right foot sitting in passenger seat. TR
