I found the price difrance to be true around here also. It seems that they add a little bit o' extra for shipping and then thay add more on top for the dealership profits. Thay all add a certain percentage and the rest of it is decided by how far from california you are. Thats where all of the parts come from, so I'm told anyway. The coil packs were $64 for me here in Pa.

The valve cover gasket you need to get from the dealer. I dont think anyone else carries them. While your at at the dealership, pick yourself up a plentum gasket you will need that also, for at the throttle body. You probably have a paper one there right now that will have to be replaced when you take everything apart.
