Nobody wants to get ripped off, the consumer or worker. There are to many variations to pin point one thing/person at fault. Could be a dishonest/overpriced dealership, dishonest worker or a customer wanted something for next to nothing. Also a lot of times the suspected price gouging is just perceived by the consumer because of not knowing the actual cost of doing business. I believe the reason most dealerships do mostly warranty work is self inflicted. Years ago when people went to dealers for general service work they were faced with constant price gouging, pushy salesmanship and they then resorted to finding cheaper smaller shops that could do good work.

Also my 06 ram 5.7 uses copper core champion plugs and it runs runs fine with them. I see no need for the more expensive plugs. I would go with what Chrysler recommends for your vehicle. It should be listed in the owners manual.
