Have had a funky smell for a while in my car. Air fresheners just couldn't quite cover it up. I pulled the old filter out which was reallll caked up with stuff and got the new one in. Not only is the funky smell finally gone, but the HVAC is a lot quieter when on full blast, and it blows the air harder. It fit great, installation was easy, and having the smell gone makes it worth absolutely every penny.
