This is my second order of these grilles and both sets went in without any issues at all. The gloss black finish is exactly what the E92 front end needs and the quality feels way better than you would expect for the price. Anyone still running chrome on their E92 is missing out on an easy and cheap upgrade.

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.
