AGENT 47 S197 Lower Grille 2005-2009 Mustang GT (W/O brake cooling kit) Our lower grill replacement gets rid of those silly fake lower scoops on your S197 and replaces them with fully functional scoops giving your front end an aggressive and purposeful look. Replacement time is less than ten minutes. Simply unclip the old one and clip the AGENT 47 one in. The grill can also be upgraded later with our high performance brake duct kit which is another easy bolt on.
