The ADRO carbon fiber rear diffuser for the Kia K5 GT and GT-Line models is one of the most aggressive rear diffusers on the market and is made from the highest quality carbon fiber that’s been measured, molded, and handcrafted to fit perfectly on the K5. Featuring eight total air strakes, the carbon fiber rear diffuser will not only make your car look a lot more aggressive, but will also help channel air under the car, slightly improving aerodynamics. This is a strong, lightweight, and functional mod for the Kia K5 that will transform the rear end of the car with ease.
