Question about 2002 Kia Sedona
Here's how I do it:
-Pull the coils out on the front bank and change those first 'cause they're easy.
-Remove air box top and intake tube from throttle body as a unit by removing 10mm bolts in air box and 10mm clamp on throttle body (unplug MAF sensor too)
-Unbolt brackets from rear of upper intake (one of them actually has to come off...the one on the left, I think...).
-Unplug all the assorted gizmo's on the plenum, and the wiper motor plug (it's sort of in the way...). The connectors are all different so there's no worry about mixing them up...
-Unbolt all of the visible 10mm bolts on top of the intake plenum that hold on ground wires and cable brackets, etc.
-Undo the plenum bolts (12mm), keeping care not to lose the lock washers from the two nuts on either end (warning, us a rag to cover the intake ports).
-As far as I can remember, you should now be able to lift the plenum up and to your right enough to get at the rear plugs. You shouldn't need to remove anything from the throttle body (cable, connectors, coolant lines...). It can be held up with a bungee cord or something. Or perhaps an assistant...
-After changing plugs, assembly is reverse of removal. You can replace the gasket between the upper and lower intake if you wish, but it's metal and usually in quite good condition. Good luck and hope this helps.

The upper intake has to be taken off to get to them. Yes it is a pain in the but, not too hard to do, just bothersome to do this to be able to change plugs. Make sure to be careful when loosening the intake as the head is aluminum and you can damage it if you take a gung-ho approach. You will need to replace the gasket but it is only around 12 -15 $ .
