Audi models use highly sensitive recirculation and filtration systems. A clogged cabin filter reduces HVAC output, increases defrost time, and allows dust and exhaust odor into the interior. The ECOGARD XC36071C restores proper airflow and protects airflow sensors and HVAC components.

Fits great. The price is good. I usually buy the more expensive ones, but this one does the job just as well. There is no more musty smell coming from my AC vents.

Saw a tutorial on how to replace the cabin air filter in my car and when I took the old one out it looked like it hadn’t ever been changed. Almost 80k miles and it was filthy and a little damp. Changed the engine air filter and put this unit in today as well and it feels like my AC and Engine are running 30 percent better from the first drive alone. The car doesn’t have a lingering odor and feels like it runs a lot smoother than before. Highly recommend to your engine air filter along with the cabin air filter, the thickness and ease of installation will save you money in the long run !

Works like it’s supposed to with a good price.

Fit was spot on. Porsche would have charged 200 to install did it in 3 minutes for fraction of cost.
Alvanetta Riley –
I ordered this so that I could replace the filter of my car. It was easy to install much easier easier than the product that was already in place. There were easy directions to describe which position to place it in for great airflow. Would recommend it and it’s high functionality for anyone!

Product as described
The size of the filter was slightly different to the one I had replaced, which was the original one.However, it managed to fit with the space, using some slight tuggling. Its a tight fit however it does work.Filter did eliminate the smells, so it does exactly whats on the tin.
