Overview

The CAP Carbon Fiber Diffuser is an aftermarket exterior enhancement for the 2016-2018 C7.5 Audi A7 S-Line/S7.

Installation is recommended to be performed by a professional, as it requires the removal of the rear bumper. Securing the diffuser may involve the use of set screws around the corners for optimal fitment.
Show original supplier description
Installation of this carbon fiber diffuser is highly recommended to be performed by a professional with experience in aftermarket products. The process necessitates the removal of the rear bumper for proper fitment. Additional set screws may be required in the corners or tabs to ensure the diffuser is securely installed and maintains its intended shape. For users integrating the diffuser's lighting features, wiring instructions are provided. The live wire is red, the ground wire is black, and the brake light wire is yellow. It's noted that the integrated LED has been updated to a refreshed, nicer version as seen in updated product images.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
