Premium Carbon Fiber Aero Range for Audi A4L / S4 B9 & B9.5

Build a coordinated exterior package with a large selection of carbon-fiber aero components for Audi A4L / S4. Every selection is named by model year, component and style so customers can clearly tell whether they are buying a front lip, rear diffuser, side skirt, spoiler, canard or exhaust-tip set.

Construction

The aero components use lightweight carbon-fiber composite construction with visible woven surfaces and a gloss protective finish. Molded contours follow the bumper, sill and trunk lines of the corresponding B9 or B9.5 body.

How to Choose

Choose the option that matches both your vehicle year and the exact body part you want. B9 and B9.5 bumper contours differ, so select only the year range listed in the option name.

Component Families

Available parts include front lips, rear diffusers, side skirts, rear spoilers, fog-light canards and quad exhaust-tip packages in multiple styling designs.

Installation

  1. Confirm vehicle year and bumper design.
  2. Dry-fit the selected part and check all clearances.
  3. Clean the mounting surfaces and transfer compatible clips or hardware.
  4. Secure using suitable screws, bolts, clips and automotive-grade adhesive.
  5. For illuminated diffusers, route wiring away from exhaust heat and use a fused electrical connection.

FAQ

Are all options the same part?
No. Each variant is a clearly named component or design.

Will B9 parts fit B9.5?
Only when the selected option specifically states the correct year range.

Can I combine several options?
Yes. Customers can combine compatible front, side and rear components for a complete exterior package.

Is professional fitting recommended?
Yes, especially for large diffusers, side skirts and illuminated components.
