Whoops never mind I saw you meant the mesh on the bumpers.

Correct me if I'm wrong but shouldn't that be already Titan silver to match grilles and good vents on a 4.8?

You can buy the silver mesh pieces from BMW they aren't expensive, but yes I think the lower mesh should match the grilles and hood vents
