Easy install !! They fit well and look good
Size: Single Slat, Color: Chrome
The grill is plastic of course but for the price it makes the car look good. I had a cracked grill and it looked so ugly. These popped right in easy install and makes the car look good again I am happy.

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.
