A+. Fits and looks like it came from BMW

Great product.

Quick turnaround

Great products!! Always fit properly

I installed this on my F82 with zero issues and it was a mile better quality than Vargas kit which I have on my F80.

They are great. Noticed pulling out the driveway once installed. Car is neutral like it should be before you need it. Feels much better on track as well.

The shipping was on point. The merchandise was of high quality.

Fitment was a bit awkward upon installation, but it works as designed. Slight turbo noise improvement 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.

Exhaust sounds good No instructions No seal ( downpipe to exhaust ) A huge washer with no explanation where it should go

Actually the best set up for the car. Perfect height and feel. Really handles better and rides smoother. Amazing quality, service and delivery. Can’t recommend carbahn enough.

The tune is perfect. Cleans up shifting and adds just enough hp for impactful spirited rides; yet not too much for a daily driver. A+.
