Replaced my plugs today- very easy!
Well, today I pulled the plugs. I had 29,549 miles on the General, and it was time. I HIGHLY recommend this as a DIY project based on what others report dealers charging for this maintenance. I've heard figures of $250.00 to well over $400.00. I paid ~$25.00 for 16 OEM Champion RE14MCC4 plugs from rockauto.com.
Here are a few post mortem thoughts:
1) Unlike other cars I've worked on, the rearward plugs were easier to pull. The plugs for #1 cylinder were blocked by the oil dipstick tube, and it was necessary to pull the airbox to access the plugs for #2 (those of you with CAI's can probably avoid that step).
2) A rudimentary socket set is all that is required. You need a 5/8" spark plug socket, a U-joint, and a 4" extension, in that order.
I would have posted pics, but wife & kids were away for the weekend and took the camera with them...
The whole process took me about 2 1/2 hours, mostly because I kept having to go back into the house for more beer...
