New APR Badges!| 04/15/2021
APR Badges are here and now available in matte silver, polished silver, and satin black! These badges are hot. They look OEM thanks to the multi-piece design and 3D-domed profile, but draw all the right attention to enthusiasts in the know. Install is a snap. Just peel-and-play. We even include a template so you don’t have to worry about a sketchy install. Some have said these badges increase the value of the vehicle, while others have made horsepower gains, but we can’t comment on either. We prefer the trunk, but this badge installs anywhere it fits!
