$235 plugs included? If so pay the man. Better his knuckles skinned than yoursget him to do the wires at the same time.
Also why go to the dealer? Joe's garage down the road can probably do as good or better job. Price out a few places.

Others have commented on difficulty with wires. I don't know why. Take a picture of both sides (you probably won't need, but just in case). Pull out the entire wiring harness. Lay on a workbench. Take another picture. Pull apart and replace with OEM wires (you know they'll fit exactly), referring to your picture for routing. Put harness back into engine, rerouting around back exactly as it came out. Reconnect as you replace each plug.

Just changed the ones on the wifes 2010 (75k). Like everyone said the driver side is a breeze. To help with the passenger rear most plug I found it helped to pull the plastic hose clips off the valve cover studs and that gave just enough room. Also helpful tip, use dielectric grease on your boots. None of hers had any and 1 (the rear most passenger side plug) pulled the metal retainer clean off the wire. Also make sure you're checking and re checking the gaps. Dont want to go back in there a 2nd time

Pull the entire passenger side flare off, literally 5 minutes and then you have direct access to the plugs. It's 5 or 6 10 mm bolts then a pull up and out. I won't change my plugs without pulling the flare.

is it better to pull the flare? or the battery tray
I just looked at it and was getting set to do it. but the battery tray look like a major pita. when you pull the inner fender flare ar you working with the jeep on lift or just laying on ground or crawler.. I am 62 and not so flexible any more. But I did put my rear bumper and tire carrier all alone I just used the brain to lift it into place with some ratchet straps it was pretty heavy,,,

I paid the dealer $295 to change all the plugs and wires on my 2008. I had them do it since I have the lifetime transmission and engine warranty. One less thing they can blame if there is an issue. I also let them do the transmission drain and fill. Small price to pay if it needs to be replaced.
