2013–2016 Audi A4 S-Line / S4 B8.5 Sedan Ducktail Style Rear Trunk Spoiler – Carbon Fiber

Give the rear end of your Audi A4 B8.5 S-Line or S4 Sedan a distinctive, performance-focused makeover with this carbon fiber ducktail rear trunk spoiler. The ducktail profile extends upward and outward from the trunk lid edge to create a bold, sculpted rear silhouette that reads as noticeably more assertive than a conventional lip spoiler.

Build

• Material: Genuine carbon fiber, autoclave cured using a 3D design and CNC moulding process for precise ducktail geometry, consistent panel quality, and an authentic weave appearance over carbon-look ABS or fiberglass alternatives
• Surface finish: High-gloss epoxy-polished top coat that showcases the natural carbon weave and resists UV exposure, moisture, and surface degradation through sustained outdoor and driving use
• Configuration: Single-deck ducktail spoiler, supplied as a single piece
• Weight: Lightweight carbon construction adds negligible weight to the trunk lid

Design & Finish

• Ducktail profile: Rises upward and outward from the trunk lid edge for a sculpted, assertive rear silhouette that reads distinctly differently to a conventional lip or deck spoiler
• Carbon aesthetic: Directional weave and gloss finish complement the sporty S-Line and S4 bodywork for a coordinated, motorsport-grade look
• Factory-style integration: Precision-molded to follow the contours of the factory trunk lid for a clean, seamless fit

Fitment

• 2013–2016 Audi A4 S-Line B8.5 Sedan (4-door)
• 2013–2016 Audi S4 B8.5 Sedan (4-door)
• Fits the factory Sedan trunk lid only — not compatible with aftermarket trunk configurations
• Body style: Sedan only — does not fit Avant or Allroad body styles

Package Contents

• 1 × carbon fiber ducktail rear trunk spoiler
• Pre-applied adhesive tape for installation

Installation

• No-drill, adhesive-mounted: Installs with the included adhesive tape — no drilling and no permanent modification to the factory trunk lid
• Surface prep: Thoroughly clean, degrease, and dry the trunk lid at the spoiler position before fitting to ensure maximum adhesion
• Alignment: Dry-fit and check the spoiler sits centred and symmetrical across the trunk lid before final adhesion
• Professional installation recommended for the best positioning, panel alignment, and finish

Before You Install

• Confirm your car is an A4 S-Line or S4 B8.5 Sedan (2013–2016) before ordering — this will not fit the Avant or Allroad
• Work in moderate temperatures and allow the adhesive to cure fully before washing the car
• Installation is reversible, but adhesive removal and re-prep may be required if the spoiler needs repositioning
