Audi A4 B9 S-Line / S4 Sedan Carbon Fiber 3D Style Front Bumper Lip Splitter Chin Spoiler 2020 - 2021

2020–2021 Audi A4 S-Line / S4 B9 Type 8W Sedan Front Bumper Lip Splitter Chin Spoiler – Carbon Fiber

Make a bold front-end statement on your Audi A4 B9 S-Line or S4 Sedan with this carbon fiber front bumper lip splitter chin spoiler. Molded for the factory front bumper, this substantial full-width splitter adds dramatic visual width and a pronounced ground-hugging forward stance — a comprehensive front-end transformation rather than a subtle trim addition.

Build

• Material: Genuine carbon fiber, autoclave cured using a 3D design and CNC milling process for precise chin spoiler 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 provides lasting UV and moisture protection through sustained outdoor and driving exposure
• Configuration: Single-piece full-width chin spoiler for the lower front bumper
• Dimensions & weight: 184 cm wide · approximately 6 kg — a substantial, full-coverage panel

Design & Finish

• Aggressive stance: Chin spoiler profile adds dramatic width and a lower, ground-hugging forward stance for a commanding front-end presence
• Full-width coverage: The 184 cm span covers the complete lower front bumper for an integrated finish with no exposed factory sections
• Carbon aesthetic: Directional weave and gloss finish complement the factory B9 bodywork for a coordinated, motorsport-grade look

Fitment

• 2020–2021 Audi A4 S-Line Sport Sedan (B9, Type 8W)
• 2020–2021 Audi S4 Sedan (B9, Type 8W)
• Fits the A4 S-Line and S4 factory front bumper only — not compatible with the standard non-S-Line A4 or aftermarket bumper configurations
• Body style: Sedan only — not confirmed for Avant or Allroad body styles

Package Contents

• 1 × carbon fiber front bumper lip splitter chin spoiler
• Mounting screws for installation

Installation

• Screw-mounted: Secures with the included mounting hardware for a secure, rattle-free fit suited to the larger panel dimensions
• Drilling required: Screw installation uses fixing points on the bumper — this is a permanent modification, not a reversible fit
• Surface prep: Clean and degrease the front bumper at all fixing points before installation
• Professional installation strongly recommended — the size and weight of this panel make correct positioning, panel alignment, and a clean, gap-free finish difficult to achieve unaided

Before You Install

• This is a large, heavy panel (184 cm · 6 kg) — plan for a second pair of hands during fitting
• Screw mounting is permanent — it requires drilling into the bumper, so dry-fit and confirm placement carefully before securing
• Confirm your car is an A4 S-Line or S4 B9 Sedan (2020–2021) before ordering — this will not fit the standard non-S-Line A4
• Front splitters sit low and are exposed to kerbs, driveway ramps, and road debris — take care when parking nose-in
