Check engine light
Style: Gloss Black Single Slat, Size: G20（2019-2022）, Style: Gloss Black Single Slat, Size: G20（2019-2022）
Looks good but will throw a check engine light on your car. The fitment isn’t perfect causing the adaptive vents to show that they are failing even though they are not

Quick fix
Style: Gloss Black Single Slat, Size: E46（2002-2005）4-Door
Easily Installed with no modification in under a minute. The finish was a little glossier, then OE.

Fits nicely and matte looks much better than gloss IMO
I previously purchased a gloss kit that had a very poor fit so I had to return it. I got this which has an excellent fit and I actually like the matte finish much better (everything else which is black on the car is also matte: weather seals, door frame etc)

Great inexpensive mod
Very easy to install, the old grill was a little difficult getting out but the new grill fit perfect and easy to install on my son's 2008 E90/328i. Looks great, best $'s for the most bang we've spent so far...
