2017–2019 Audi A4 S-Line / S4 B9 Sedan Front Valance Lip – Carbon Fiber

2017–2019 Audi A4 S-Line / S4 B9 Sedan Front Valance Lip – Carbon Fiber

Sharpen the front-end stance of your Audi A4 B9 S-Line or S4 Sedan with this carbon fiber front valance lip. Molded for the factory front bumper, it adds a wider, more ground-hugging forward presence to the lower front end while keeping the refined character of the factory B9 body design.

Build

• Material: Genuine carbon fiber, autoclave cured using a 3D design and CNC moulding process for precise valance geometry, consistent panel quality, and an authentic weave appearance over carbon-look ABS or fiberglass alternatives
• Surface finish: High-gloss epoxy-polished top coat that showcases the natural carbon weave and resists UV exposure, moisture, and road debris through sustained outdoor and driving use
• Configuration: Single-piece valance lip for the lower front bumper
• Panel width & weight: 182 cm across · approximately 1.05 kg

Design & Finish

• Aggressive stance: Valance profile lowers and widens the visual stance of the front end for a more planted, performance-oriented forward presence
• Full-width coverage: The 182 cm span covers the lower front bumper for an integrated finish with no exposed factory sections
• Carbon aesthetic: Directional weave and gloss finish complement the sporty S-Line and S4 bodywork for a coordinated, motorsport-grade look

Fitment

• 2017–2019 Audi A4 S-Line B9 Sedan
• 2017–2019 Audi S4 B9 Sedan
• Fits the factory front bumper only — not compatible with aftermarket or non-B9 bumper configurations
• Body style: Sedan only — not confirmed for Avant or Allroad body styles
• Check your bumper shape against the product images before ordering — B9 front bumpers differ between trim levels

Package Contents

• 1 × carbon fiber front valance lip
• Adhesive tape for installation
• Mounting screws for installation

Installation

• Two mounting options: Fit with the included adhesive tape for a reversible install, or with the included screws for a more permanent, secure fitment
• Surface prep: If using adhesive tape, thoroughly clean, degrease, and dry the front bumper before fitting to ensure maximum adhesion
• Alignment: Dry-fit and check the valance sits centred and even across the bumper before committing to either method
• Professional installation recommended for correct valance positioning, panel alignment, and a clean finish — particularly if using the screw-mount option

Before You Install

• Verify your bumper shape against the product images before ordering and confirm your trim level
• Screw mounting is permanent — it requires drilling into the bumper, so decide on your method and confirm placement before starting
• Front lips sit low and are exposed to kerbs, driveway ramps, and road debris — take care when parking nose-in
• Adhesive installation is reversible, but removal and re-prep may be required if the valance needs repositioning
