The MPC Bumper Diffuser is designed to allow air to pass freely thru the rear bumper, elimination excess drag. Our Diffuser comes with both a bolt kit and rivets to allow you a choice of installation. We offer this in a 1-piece version (4" x 44") or a 2-piece version (4" x 19")
MPC Bumper Diffusers are precision CNC machined, and finished with a gloss black powdercoat. Like all MPC products, these are built right here in our shop in the USA.
