Review on Mann Filter CUK 2533-2 🚗 Carbon Cabin Filter with Enhanced Activation by Scott Mauri

Excellent filters, replacement for the original BMW 535i series. They come with a printed guide with photos showing how to swap them out step by step. There are also many videos on YouTube. They're quite difficult to install, not because of the filters themselves, but because of BMW's over-engineering. You will need to remove the 2 10mm screws and 1 torx screw securing the knee panel that contains the airbag(!). The filter housing then has 4 more Torx screws. The filters are excellent, absolutely no different than OEM factory BMWs (except for the missing BMW logo). Mann is a highly respected German company.
