Swivel spark plug socket, locking extension, extension
Big 3/8" ratchet, stubby 3/8" ratchet

Remove intake box
Reposition wire harness
Remove coils
Remove plugs
Coat tips of plug threads and coil bolt threads with anti seize
Install plugs
Install coils
Reposition wire harness

Note: the wire harness cover does not have to be removed, I removed it to show a good view of the clips.

Note 2: I didn't show the small vac line get disconnected prior to removing the intake box. It does have to come off.:)
