Does NOT fit BMW F22 2 Series
Style: BE-472P 1-Pack
Does not fit BMW F22 2 Series. The housing for the cabin air filter is curved and the OEM cabin filter is flexible like an accordion. This filter has the correct dimensions but it does not flex so it will not fit the housing properly. You MIGHT be able to jam it in but not without damaging the filter and at that point it would be practically useless. Buy one that is OEM spec and confirm it can flex for proper fit.

It’s ok
Style: BE-157P 1-Pack
Not a perfect fit, decent quality. Fair product since it was significantly cheaper than the manufacturer filter.
