Great replacement for when the originals break, because they will.

It fits, but just barely, so it's good that it is sturdy
Style: Matte Black Single Slat, Size: E46（2002-2005）4-Door, Style: Matte Black Single Slat, Size: E46（2002-2005）4-Door
First and foremost, this part is a fairly poor copy of the OEM part. It's close enough to look good from about 20 feet away, but on close inspection, it has gaps all around.
It doesn't follow the curve of the opening properly, and the contours aren't quite right, making it so the outer top corners aren't recessed the way they are supposed to be (see pictures). Some of the tabs don't interface with their mating surfaces because the part is about 5mm too small in the y-axis (see picture).
That said, after ordering another similar knock-off, this one is the better of the two. The matte finish is truly matte. The grill slats are thick and beefy, like OEM. The tabs are stout and flexible, not brittle. After much fussing with installation, you should be able to bend your hood tabs (not that you should have to) so all tabs will lock in place.
The hardest part for me was getting the outboard-most tab to properly snap in, since the outer top corner of each grill doesn't sit flush inside the recessed relief where it's supposed to sit.

Why pay OEM prices? These kidney grills fit excellent!
Style: Matte Black Single Slat, Size: E46（2002-2005）4-Door
Was a bit skeptical but the fit and quality are excellent. The do not wobble around or fit loosely. Highly recommended.
