If you are going to DIY the plugs, I would not replace the coils just for the hell of it. Coils fail vary rarely. If one fails, then replace it as necessary. If you don't DIY then maybe there is a cost savings if you consider the labor involved in replacing a coil; and doing all six would make sense in that case, but your adding at least $200 in parts cost for just a plug chnage.

BTW, my car has 196,000 miles on the orginal coils.
