Give the rear end of your Audi A4 B8.5 S-Line or S4 Sedan a distinctive, performance-focused makeover with this genuine carbon fiber ducktail rear trunk spoiler, precision manufactured using a 3D design and CNC moulding process with full autoclave curing. The ducktail profile is one of the most recognisable and purposeful spoiler designs in motorsport — extending upward and outward from the boot lid edge to create a bold, sculpted rear silhouette that is immediately more assertive than a conventional lip spoiler. The high-gloss epoxy polished surface showcases the natural carbon weave finish and provides lasting protection against UV exposure, moisture, and surface degradation. Adhesive tape is supplied for a clean, no-drill installation with no permanent modification required to the factory boot lid.

Features:

• Genuine carbon fiber construction – autoclave cured using 3D design and CNC moulding for precise ducktail geometry, consistent panel quality, and high structural integrity
• High-gloss epoxy polished surface finish – showcases the natural carbon weave and resists UV exposure, moisture, and surface degradation over sustained outdoor and driving use
• Single deck ducktail spoiler profile – a bold, motorsport-inspired rear boot lid design that adds a dramatically more assertive rear silhouette to the A4 B8.5 and S4 Sedan
• Adhesive tape installation – clean, no-drill fitment with no permanent modification required to the factory boot lid
• Lightweight carbon fiber construction adds negligible weight to the boot lid
