This elegant and aggressive design brings the look of your vehicle to a whole new level. Beri-Backer builds each kit from a UV resistant black textured .25" thick plastic that is durable, and easy to wash. These diffuser kits are now equipped with interchangeable fin technology. Simply unbolt a fin from the baseplate and swap it out for a different style. If you ever get tired of the look, or damage a fin, spare fin packs are available for purchase on ECS Tuning!
