Ok substitution for the value
Size: Single Slat, Color: Chrome
Bought these for my 2004 M3, quality is good, fitment is OK, some gaps around the edges but you cant tell unless you look very closely. About as expected for the cost.

Last about a year ishhh
Size: Single Slat, Color: Glossy Black&M-Color
Plastic mold isn’t as straight as it should be, the clips don’t line up like oem. Product is wiggly. Had on car for over half a year.
Hasn’t faded. Just wish the fitment was better.
Update: the grill lasted about 1 1/2 years, it began to fade, and I had a slat crack, no evidence of impact. I ended up buying a better made product and replaced this grill.

Fits a 2001 330!
Size: Single Slat, Color: Black, Size: Single Slat, Color: Black
The grill in my old 2001 330 broke off and I was really happy to find a nice looking replacement at an inexpensive cost. The black looks really sleek on it and has breathed some new life into it. Next up is to replace the emblem.
