Just had the dealer do the 30k service on my jeep (bought the maintenance plan so I wouldn't have to do anything) and it took them about 5 hours to do, which is about par for the course considering all that was done. What shocked me was that along with replacing all 16 spark plugs, they actually changed out all of the wires as well. Anyone know why?

Not sure either, I guess since there are secondary coil packs on top of each set of spark plugs, they must be more condusive to wear? Anyone know?
