Review on 🚗 BMW Cabin Air Filter - Mann-Filter CU 6724: Reliable Air Filtration for Select BMW Models by Rudy Barron

I picked up my car (2000 323i) and wasn't sure if the cabin air filter had ever been changed - it certainly didn't smell like it. When I took the old one off, I realized why the air smells so musty! This Mann filter fits PERFECTLY and after a few minutes everything smelled cleaner. A huge and very pleasant difference – activated charcoal actually seems to work. For the money it can't be better. Opening a can of tuna is probably really harder. There are some good videos on youtube on how to change this to E46 if you are unsure. No tools are required as all you have to do is undo the three clips that hold the top cover in place. Everything is easily accessible and takes about 2 minutes. Just watch how you place the filter and that's it. I can only imagine how much money they can charge for this at a mechanical shop/dealer. And it really doesn't take more than 2-3 minutes.
