Didn’t fit my 2008 Mercedes C300 4matic sport.
I bought another one on Amazon from a different company and it did fit. Eochi or something brand.

OEM quality
BMW dealer wanted $300 to replace the cabin filters. Watched a 5 minute video and ordered these up. Look identical to OEM and easiest cabin filters I've installed.
Save yourself a ton of money and install these yourself. BMW quality without the BMW price.
