Show original supplier description
The Maxton Design Side Skirts Diffusers are designed to enhance the visual appeal and aerodynamic performance of your Audi S5 or A5 S-Line F5 Coupe. Constructed from durable ABS plastic, a material commonly used in OEM automotive parts, these side skirts offer excellent impact resistance, scratch resistance, and shock absorbency. This ensures a long-lasting finish and robust performance. The product is available in three distinct finishes: gloss black, textured black, and carbon look, allowing you to match or complement your vehicle's existing aesthetic. Maxton Design ensures perfect fitment through 3D laser scanning of each vehicle model. The diffusers come with a mounting manual and mounting kit, and are ready for installation. However, professional installation by experienced auto body shops is highly recommended to ensure proper fit and finish. Note that preparation work may be required if you choose to paint the textured version. This product is certified by TUV for material quality and is treated with a UV protection coating to prevent fading and degradation. It is designed specifically for the Audi A5 B9 (2017-2019) Coupe with the 2.0T engine and the Audi S5 B9 (2018-2019) Coupe with the 3.0T engine.
