2017–2019 Audi A4 / A4 S-Line / S4 B9 Sedan R Style Ducktail Trunk Spoiler – Carbon Fiber

Sharpen the rear end of your Audi A4 or S4 B9 Sedan with this R Style carbon fiber ducktail trunk spoiler. Molded to follow the natural curve of the decklid, it adds subtle aggression and improved trunk definition for a more performance-driven profile without overpowering the clean factory lines.

Package Contents

• 1 × carbon fiber ducktail trunk spoiler
• 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 a B9 Sedan (2017–2019) before ordering — this is moulded for the Sedan trunk lid and will not fit the Avant
• 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
