I’ve got a 21 RDX A-Spec and was wondering if the matte black diamond grille can be swapped with one of the glossy black ones instead? I wasn’t sure if that was a separate piece or if the whole grille would need replaced.

 

I'm not 100% sure but perhaps the PMC Edition grill is the one you're looking for in gloss black?

Realize the grill surround (#3 in pic) is a different part for both A-Spec and PMC - I don't know if they're interchangeable or not.

It seems the Advance package grill is the same one as the PMC one, based on parts:

This is exactly what I was having a hard time finding. Thanks for the help!
