I finished replacing the spark plugs on my 2500 HEMI last night. I had a bit of a scare. I could not find one of the bolts for the number #7 coil. Fortunately this morning I found it on top of the engine. I put a blanket over the radiator to lay on but I think foam would be better. I found using an air ratchet helped a lot in dealing with the driver's side rear plugs. I work on four plugs at a time, not sure that is the best way but it seemed to work OK for me.

 

Good for you man. I was really sore after doing mine also. Dosent help me that I am short and the 2500 sits higher as it is haha
