why are the cabin air filters so expensive!

Have you noticed it working? Is there any change to the indicator light, or...?

the light shouldn't change, apparantly there is some sensor that is smart enough to detect excess particles in the air and switch from "recirc" to "fresh" and then back. (or the other way around, can't remember which setting is default)

When it arrives, can you please confirm that it's a set of 4 and the fitment is correct? Thanks!

Confirming this is the part and the box comes with 4:

Funny, surprised me when I opened it.

Yup, my set is the same.

The filters are dark so it is hard to tell when you are due for a replacement. Unlike the white cabin filters on most cars which turn dark as they get dirty.

I am thinking the dark color is charcoal sprinkled on top. Anybody know for sure? Could be why they are so expensive.

checked manual and this filter is targeted to be changed every 2 years.

just got back from my 2 year dealer visit and mine still looks dark. so who knows if they check it much.

I drive with my windows down most of the time so no biggie to me

These do have activated charcoal in them

It's unclear on the item description, is this for the set of 4?

That PN/Link doesn't show fitment for our M3's
Cross checked with another BMW parts site as well.
