2017–2019 Audi A4 S-Line / S4 B9 Sedan Single Deck Rear Trunk Spoiler – Carbon Fiber
Add a refined finishing detail to the trunk lid of your Audi A4 B9 S-Line or S4 Sedan with this carbon fiber trunk spoiler. The single-deck profile complements the factory body lines with a subtle yet purposeful upgrade that lifts the rear profile without an overly aggressive appearance.
Build
- Material: Genuine carbon fiber, CNC machined and vacuum moulded for precise spoiler geometry, consistent panel quality, and an authentic weave appearance over carbon-look ABS or painted plastic 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 spoiler, supplied as a single piece
- Weight: Lightweight carbon construction adds negligible weight to the trunk lid
Design & Finish
- Understated profile: Clean, refined single-deck line that adds a performance-inspired finishing detail 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
- 2017–2019 Audi A4 S-Line B9 Sedan (4-door)
- 2017–2019 Audi S4 B9 Sedan (4-door)
- Fits the factory Sedan trunk lid only — not compatible with aftermarket trunk configurations

Installation
- No-drill, adhesive-mounted: Installs with the included adhesive tape — no drilling and no permanent modification to the factory trunk lid

- 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
