Fitment was a bit awkward upon installation, but it works as designed. Slight turbo noise improvment as well. Reason: was slightly concerned about this CarBahn filter being noticeable thinner comparing to both, the stock/OEM 'Mann' & the 'aFe dry-series' filter(s) those mentioned ones were both used and pulled out of my X3 M40i. I service the air filter every year on my tuned 2020 X3 M40i so this worked out great.
