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

Add a refined finishing detail to the trunk lid of your Audi A4 B8.5 S-Line or S4 Sedan with this carbon fiber rear trunk lip spoiler wing. Molded for the factory trunk lid, its clean, purposeful profile complements the factory body lines and lifts the rear roofline without an overly aggressive appearance.

Build

• Material: Genuine carbon fiber, autoclave cured using a 3D design and CNC moulding process for precise spoiler geometry, consistent panel quality, and an authentic weave appearance over carbon-look ABS or fiberglass alternatives
• Surface finish: High-gloss epoxy-polished and UV-protected finish that showcases the natural carbon weave and resists UV exposure, moisture, and surface degradation through sustained outdoor and driving use
• Configuration: Single-piece lip spoiler wing
• Dimensions & weight: 129 cm wide · approximately 1.9 kg

Design & Finish

• Understated profile: Clean lip wing that adds a performance-inspired finishing detail to the trunk lid without altering the character of the factory body design
• 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 rear trunk lip spoiler wing
• Adhesive tape for installation
• Mounting screws for installation

Installation

• Two mounting options: Fit with the included adhesive tape for a reversible install, or with the included screws for a more permanent, secure fitment
• Surface prep: If using adhesive tape, 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 committing to either method
• Professional installation recommended for correct positioning and a clean, gap-free finish — particularly if using the screw-mount option

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
• Screw mounting is permanent — it requires drilling into the trunk lid, so decide on your method and confirm placement before starting
• Work in moderate temperatures and allow the adhesive to cure fully before washing the car
• Adhesive installation is reversible, but removal and re-prep may be required if the spoiler needs repositioning
