It's a Filter!
Size: 97133L1000&28113AA100
Fit great! Just look on youtube how to put in! I'm not in a particularly dusty area, but the air cabin filter was a disaster after only a year. Will buy again!

Size: CF11966&CA12166
Perfect fit. Easy to install. Good price. When changing the cabin filter the screw removal is a little easier if you notch out the plastic in front of it. Its behind the glove box and is not noticeable.

Excellent Air filter - Easy installation.
Style: BE-743 1-Pack
Excellent AC and Heater Cabinet odor defense air filter. I noticed immediately the smell coming out of the vents was fresher and the musty smell that was coming from the vents was crisper and cleaner. Very easy installation that you can do yourself and don’t need to pay a shop to do. The price is one of the best online and coms in quickly. It’s very sturdy, filter quality is excellent and it definitely improves the air quality and flow in your car. Fits perfectly like any OEM filter, this is a great buy for the price of an installation that will take you Les then 10 minutes to do yourself.
