Where are the spark plugs on a 2004 Kia Sorrento

Question: Where are the spark plugs located on a 2004 Kia Sorrento ? Answer: I'm assuming you've got the 3.5L V6? When you remove the upper intake there are two brackets on the back (five 12mm bolts, I think...) that need to be removed, as well as the readily visible ones on top, in order to lift it up. And once you get it loose be sure to put a rag or something over the intake ports; trust me... it can all go very wrong if you don't! 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 gizmos 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 (see above warning about using 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. I think that's all there is... I've done a few, but it's been a couple of months since the last one.
