Had my 4 runner serviced at a Toyota dealer, oil change, and the tech showed me the a/c filter suggesting it needed changing. I told him to go ahead and was shocked when I went to pay the bill. They were charging me $49.00 for a very simple little filter. It's only about 8"'s square and looks similar to the plastic webbed home a/c unit filters. I could see maybe $10 for the unit which probably costs 50 cents to make. I told them to take their filter off and stuff it.
