Here are 4 main pictures when removing spark plugs in my '04 Sedona.
When the plastic engine cover is removed, the front three plugs are underneath the 3 ignition coil packs.
After taking off all of the bolts and tubes and brackets, you can swing the intake to the side. the throttle linkage is still attached.
The hardest part is removing the rear fasteners of the intake. I used a mirror to find the bolts. You will have to feel around, but it can be done.
The rear spark plug boots are connect to the front coils. Plug straight up to remove without breakage. It is pretty hard if they have not been touched for a while.
Hope this helps,
