I love my 2001 E46 (325i), but one challenge is that the plastics no longer remain "dry" in the summer heat, instead becoming a sticky mess. Picked this up to replace my existing cup-holder. I was optimistic that the black carbon fiber mesh would blend in with my otherwise black interior, but it's not the same shade of black, so the new part looks a bit out of place. No worries, I just need more carbon fiber replacement components! This fits perfectly, snaps into place, and is definitely an improvement over ~25-year old plastic. Great value too, an inexpensive upgrade that has real functional improvements -- items in the cupholder no longer get discolored with "sticky" plastic in the sun.

This filter fit just right on my FJ cruiser. Snuggle fit and no issues. You can't tell this apart form other cabinair filters. Smells like the same clean smell when you first change it.
