My local Ford dealer has always been good to me as far as service goes. I think i remember seeing that there are some people on here that work at dealerships so i thought i could get an inside opinion on this. I got a set of coupons in the mail for service. There is one that is for $89.95 and includes synthetic oil and filter, fuel filter, air filter, rotate tires, top off fluids and all the little check this and check that stuff. Pretty good deal i think. I told the service guy that i had a k&n filter so i dont need that changed BUT i do need a new cabin filter and wanted the cost of the air filter to be deducted from the cabin filter if there is a price difference. From his reaction it didnt seem likely. Why would that be a problem ? If the price i am paying includes the air filter and they arent going to replace it then i am going to tell them to just throw it on the front seat and i'll take it home, but i dont see why they cant substitute a cabin filter.
