S4 Style Rear Valance Diffuser for Executive Sedans
Transform your rear profile with the s4 style rear valance diffuser b8.5 set from Kubay Design. We engineered this custom lower apron component specifically for facelift executive sedan and avant platforms produced between 2011 and 2015. As a result, this complete rear valance diffuser package upgrades original base rear styling into a sporty performance stance featuring dual vertical fins and a silver horizontal trim line.
Our manufacturing specialists injection-mold every rear valance panel using high-impact, flexible ABS plastic finished in dark grey with a contrasting silver upper accent strip. Therefore, this lower rear apron assembly withstands high-temperature exhaust heat, road stone debris, and extreme weather elements without warping or fading over time. In addition, OEM mounting clip locations ensure a precise fitment against factory rear aprons. You can explore complete exterior styling accessories in our Shop or inspect custom conversions on Our Projects.
Engineered Diffuser Architecture and Dual-Outlet Cutouts
We precision-craft every Kubay Design rear diffuser unit to deliver authentic S-line executive presence across performance sedans and avants. Because of this targeted component molding, swapping out your original lower valance panel remains completely intuitive for professional installation technicians.
The complete package includes one grey rear valance diffuser panel with integrated vertical fins and a silver accent trim strip. Designed without integrated tailpipes, this panel features dual-outlet side cutouts that accommodate factory tailpipe configurations or custom dual exhaust tips seamlessly.
Vehicle Compatibility and Custom Installation Notes
This S4-style rear valance diffuser package offers direct OEM-style replacement fitment across 2011–2015 B8.5 facelift executive sedan and avant platforms across standard, sport, and s-line trim levels. Note that B8 pre-facelift platforms (2007–2011) feature different lower valance clip geometry and apron contour lines, making diffusers non-interchangeable across facelift generations.
Because exhaust tailpipe spacing and PDC sensor locations vary across regional specification packages, we strongly recommend submitting your Vehicle Identification Number (VIN) and current rear photos for fitment confirmation. Therefore, these custom interior packages for W447 vans and executive sedans deliver complete visual coordination inside and out.

Worldwide Freight and Multi-Layer Packaging
We pack every rear diffuser panel securely inside protective cushioned wrapping and reinforced cardboard shipping containers with custom corner foam braces to safeguard delicate mounting tabs and silver trim surfaces during international transport. In addition, we arrange global express air freight via UPS or DHL with full tracking provided after dispatch.
