Use RTV to secure
Style: Gloss Black Double Slats, Size: E90（2009-2011）
Fitment is okay, the bottom clips of the grill don’t really “clip” in to the bumper. Old Amazon grills flew off since I only used double sided tape to secure them. I used black RTV to secure these ones and they ain’t flying off this time. Over all would buy again.
