I bought this set with low expectations to replace my OEM grill which was falling apart and getting loose. I thought, not much to lose. They actually turned out to fit and look great. Just one tip-- when installing, be sure that you are correctly positioning the tension clips to be in contact with the end of the hood notch. There are a lot of Youtube guides you can find online to help you with it. Otherwise, they will just be totally loose and not fit correctly.

Easy install !! They fit well and look good

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.
