Didn't work for me
Color: Premium-CF9846A
I could not use this. After buying it I found out I had to cut some parts to replace it and decided to return it instead.

★★★★★ – Great Quality Cabin Filter for the Price Installed this Puroma cabin air filter in my car and immediately noticed cleaner airflow and less odor coming through the vents. The activated carbon really helps with smells and dust. Installation was quick and easy, only took a few minutes. Great value compared to dealership prices. Would definitely buy again.
