Mesh-Vented Carbon Fiber Rear Diffuser for Audi A5 S Line / S5 B9
Upgrade the rear profile of your Audi with this mesh-vented carbon fiber rear diffuser, designed for compatible 2017–2019 Audi A5 S Line and S5 B9 rear bumper configurations. The full-width one-piece design combines a long horizontal mesh opening with a multi-fin center section and large left and right exhaust openings.
Unlike rear bumper side splitters or LED-equipped diffuser designs, this rear diffuser uses an integrated full-width layout with a clean mesh-vented upper section and multiple vertical fins through the center.

Mesh-Vented Multi-Fin Design
A long horizontal mesh opening runs across the upper center section of the diffuser, creating the most distinctive visual feature of this design. Below it, multiple vertical diffuser fins form a deeper and more defined center section while maintaining a balanced full-width appearance.
The mesh-vented multi-fin design also helps distinguish this product from other Audi A5 / S5 B9 rear diffuser options, including LED brake-light diffusers and different full-carbon or FRP diffuser styles.
Full-Width Rear Bumper Design
This product replaces the visual profile of the complete lower rear bumper section rather than adding small individual corner pieces. The integrated left and right exhaust openings, center fins and upper mesh section form a single continuous rear diffuser assembly.
If you are looking for separate rear bumper corner splitters instead of a complete diffuser, confirm that you are selecting the correct product before ordering.
Gloss Carbon Fiber Finish
The visible woven carbon fiber surface features a gloss finish that highlights the curvature of the outer sections, center fins and upper vent surround.
Because the diffuser uses model-specific mounting points and follows the factory rear bumper shape, test-fitting is recommended before final fastening. Professional installation is recommended for proper alignment and secure mounting.

Carbon Fiber Parts for BMW, Mercedes-Benz, Audi & Porsche
Modern performance cars are particularly well suited to carbon fiber styling. Many upgrades are developed around factory bumper shapes and popular performance packages, making it possible to create an appearance inspired by high-performance factory models while retaining the original character of the vehicle.
BMW owners can explore carbon fiber styling for M Sport and M models, while Mercedes-Benz customers can find parts for AMG-style applications. Audi and Porsche vehicles can also be upgraded with front splitters, diffusers, spoilers, mirror covers and other exterior carbon components.
Product compatibility varies by model, generation, body style and factory equipment. Always review the individual product description and fitment information before ordering.
Real Carbon Fiber Styling
Carbon fiber has become one of the most recognizable materials in premium automotive design. Its woven surface provides a technical appearance that works particularly well with performance vehicles, sports cars and luxury models.
Different products may use different construction methods, finishes and carbon patterns. Listings can include glossy or matte finishes, exposed carbon fiber components, carbon overlays and composite parts with carbon fiber surfaces. Exact material specifications are provided on the individual product page whenever supplied by the seller.
Build a Complete Carbon Fiber Exterior
One of the best ways to upgrade a vehicle is to treat the exterior as a complete design rather than adding unrelated parts individually. A front splitter can be paired with side skirt extensions, a rear diffuser and a spoiler to create a consistent appearance around the entire vehicle.
Smaller upgrades such as mirror covers or trim pieces can also be used as a starting point before moving to larger components such as hoods, diffusers or full body kits.
Lux Carbon makes it easier to browse multiple styles and applications in one place, allowing buyers to compare available carbon fiber automotive parts from independent sellers before choosing the components that best match their vehicle.
Find Carbon Fiber Car Parts for Your Vehicle
Start by selecting the vehicle manufacturer, model and generation whenever this information is available. Pay particular attention to differences between standard bumpers, sport packages and performance variants because exterior components are often designed for one specific configuration.
Whether you are looking for a subtle carbon fiber accent or planning a complete exterior conversion, this collection provides access to carbon fiber parts for a growing range of premium and performance vehicles.
