It works as expected
Size: 8.3" x 9.3" x 1.3"
Great. It does block air flow by a bit, but it is ok, if you don't need strong air blowing your face at maximum setting all the time.

Great cabin filter for 2019 Acura RDX
Size: 8.3" x 9.3" x 1.3"
When I have my car serviced at the Acura dealership, they routinely recommend that the cabin filter be replaced. As we all know, a dealership is going to charge an arm and a leg for a basic service. Therefore, I have been replacing the cabin air filter myself for the past few years. I like BOSCH products and when I found this filter on Amazon, I knew that was the one to purchase for my 2019 Acura RDX. The filter fits perfectly in its location in the glove box. It literally takes less than five minutes to swap out the old filter for the new. I will continue to use this product while I have the RDX.

Perfect fit, easy installation.
Size: 8.3" x 9.3" x 1.3"
This part fits perfectly. Directional flow is printed on the part however you need to confirm which way air flows in the actual air box. The easiest test is to run the a/c with the filter out, wet a finger, and stick in in the air box to see which side the air blows cold. Then just install this part in the air flow direction as printed on the part. I have not noticed a difference in air quality yet, however I imagine being a HEPA filter, this will do wonders keeping pollen out of the car. Installed this in a 2011 Honda CR-Z. Easy installation. Part looks high quality which is fitting for Bosch.

Great filter, but doesn't fit 2013 Honda Fit without modification
Size: 8.3" x 9.3" x 1.3"
Right off the bat: I don't have any airflow problems with this filter. It works great, the air is noticeably cleaner, and airflow has not been meaningfully reduced. However, it doesn't fit my air filter holder very well. The ' air filter holder' (a plastic tray that slides horizontally into the air flow system) has two plastic fringes on either side of the tray, which each have two small notches in them, a few inches apart from one another. This appears to act as a sort of 'key' by which you can gauge you are putting the filter in with the correct alignment. On an OEM filter, the slots line up with two strips of material that stretch across the length of the filter, which themselves rest within the slots. However, the slots don't line up with the strips on this filter. I had to cut the fringes so that the slots in them are wider, so the strips would fit in them. Without doing this, the filter wouldn't press down into the tray. Having done that, and the filter now rests flush in the tray, there are still marginal gaps around the perimeter of the filter. It's a millimeter or two too small for the tray, so there is some airflow around the filter. This could be rectified by wrapping insulation tape or something around the edge of the filter, or could be ignored if you're not super picky. I haven't added any wrapping to get an airtight seal, and even with that gap I still noticed that the air is way better. So ultimately, it didn't fit exactly, but it fits 90% of the way and, with some finagling, is a superior filter by any other measure.

Don't overlook this important bit of maintenance
Size: 8.3" x 9.3" x 1.3"
Cabin air filters get dirty and gross quicker than you realize. I recommend changing them twice a year. Bosch is a quality brand, very happy with it.
