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. INSTALLATION NOTES We recommend starting from the center of the diffuser, making your holes & installing fasteners, then working your way out towards each end evenly. This process helps to ensure the diffuser will be flush with the curved surface of the bumper. • Allows Air to Pass Through Rear Bumper, Eliminating Drag • Includes High Grade Bolts & Rivets for Installation • Built from Aircraft Grade 6061 AL • Built in the USA
