Changing spark plugs in V6?

I just changed the plugs on my Sorento V6 and it was a fun challenge. Take a good look at all the connections and don't forget that 14mm bolt around the rear passenger side. It helps to remove (or at least shift forward) the battery. Then remove the air cleaner box and throttle body to give yourself room to shift the plenum upwards and out of the way. You'll also want to replace the rubber gasket between plenum and lower intake. I took pictures of all the hoses and electrical connections before disassembly in case I forgot some sequence when putting everything together. The old plugs were tight (90K miles) so make sure you use thread lube on the new ones.

Interesting aside - has anyone noticed how cruddy the intake valve bodies look? I hear this is a symptom of the GDI system - no fuel hits the back of the valves to spray them off.
