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.

Great alternative to OEM model

Works great for my car. Really didn’t see a difference between these ones and the OEM ones. It provides good value with easy installation.

pretty good for price!

Great item with easy install, drops right in for a perfect fit! the quality is up there for its money, but certainly isn’t going to be your top of the line. however it gets the job done and has a prettt decent air flow for its price!
