I just ordered the parts from Morristown BMW. Looks like the 4.6is spoiler trim is a bit different than the painted part on the 4.8is bumper (see pics).

4.8is Full Bumper (colored trim all around the lower mesh)


4.6is Bumper Trim (does not go around the lower mesh)


I like 4.6is trim because it's cheaper and much much easier to install than the complete front 4.8is bumper.

I'll have to choose between the Decorative Skid Plate or the 4.6is front bumper trim because you can't have both......Depending on how it looks, I may just remove the Decorative Skid Plate.
