Description
Transform the rear profile of your Audi B9.5 S4 with the aggressive styling and premium quality of the Canadian Auto Performance V1 Carbon Fiber Diffuser. Designed specifically for the facelifted 2020–2025 B9.5 S4, this diffuser enhances both form and function with its motorsport-inspired design and integrated LED brake light.
Handcrafted using high-quality carbon fiber, the V1 Diffuser features a bold and aerodynamic shape that complements the S4’s factory lines while adding a more assertive, performance-driven presence to the rear bumper. The included center-mounted LED brake light not only adds a race-inspired visual touch but also enhances visibility and safety.
