BOSCH 6025C HEPA Cabin Air Filter - Compatible with Select Audi A4, A4 Quattro, RS4, S4

I was looking for a good-quality HEPA filter to keep the pollen and dust down in my car, so I chose and installed this in my Audi B7 S4 Avant. It took less than 5 minutes, and was very easy. It is much more cost-effective to DIY with a somewhat more expensive (but much higher quality) cabin air filter than to just have your mechanic do it for you. If you need a pointer on how to do it, check out Total Technik's YouTube channel for "How to change cabin filter".

Super!

First off this Cabin Filter air flow is Perfect did not notice any decrease like other mentioned on there post so if you have a 2007 Audi A4 2.0T air blows strong in these cars. Filter seems a little bit less strong on the sides but right after the snug fit i put everything back together and turned on my car put the A/C and Heaters to full max the smell was AWESOME!!!!! I tried all the functions blasting the air and did not notice any performance decrease in air blowing ,smells cleaner and fresh only time will tell but for now Bosch Cabin Hepa filter is my go to Filter!

This size is totally wrong for my 2006 Audi A4 Quattro. I threw away the packaging too soon so I can't even return it. A total waste of money and I feel scammed. Huge disappointment.

This is clearly the "next generation" of auto cabin air filters. You can just see its "different", and the quality is there right. Very nice product. Hard to tell the air smells better or is cleaner, but this filter is so much better than my previous one. We'll see, but so far so good.
