Do not let your dealership overcharge you for the work they did not perform. Use this to change cabinets air filter yourself. I noticed that my old cabin air filter was used both sides when I pulled it out to install this one. Not cool. I think this cabin air filter works as expected and air quality is definitely improved shortly after installation.
