Important: current 2023 fitment data specifically confirms selected A4 Quattro Sedan trims. Fitment should not be assumed for every 2023 A4 configuration.

This product should also not be assumed to fit Audi S4, A4 Avant or vehicles using a different trunk-lid configuration unless separately confirmed.

Carbon Fiber Construction

The spoiler is manufactured from carbon fiber with a visible woven surface and a gloss clear-coated finish. The exposed carbon pattern gives the trunk area a more distinctive appearance while keeping the component lightweight.

A UV-protected clear coating is applied over the carbon surface to help maintain the gloss finish during normal exterior use. The carbon weave and surface finish are also useful visual points to check when inspecting the product before installation.

Designed Around the A4 Sedan Trunk Profile

This GT Style spoiler follows the rear deck-lid shape of compatible Audi A4 Sedan models. Its shape is intended to sit along the trunk edge rather than function as a universal bolt-on wing.

Because trunk curvature and exterior specifications can vary between model years, trims and markets, product-specific fitment should always take priority over general B9 or B9.5 platform assumptions.

Add-On Installation

This trunk spoiler is designed as an add-on exterior component and is supplied for adhesive installation. Correct surface preparation and careful test fitting are recommended before final installation.

Before installation, check:

• Trunk-lid curvature and contact area
• Left-to-right positioning
• Alignment with the rear deck edge
• Clearance around the trunk opening
• Mounting surface cleanliness
• Existing factory spoiler or trunk accessories

Do not complete final installation until the spoiler has been test-fitted and its position has been confirmed. Professional installation is recommended if you are unfamiliar with fitting exterior body components.
