If you aren't changing your own air filters in your vehicle you should be. Air filter swaps are a huge ripoff if you get the dealer to do them. Granted, most maintenance at dealerships is a ripoff BUT it takes all of five minutes if you don't know what you are doing, most of which is watching the youtube video telling you how to do it, and maybe a minute or two if you do know what you are doing. Save yourself some cash.
