2017–2019 Audi A5 S-Line / S5 B9 Front Bumper Diffuser Lip – Carbon Fiber
Make a commanding front-end statement on your Audi A5 S-Line or S5 B9 with this carbon fiber front bumper diffuser lip. Spanning 180 cm for full-width lower coverage, it adds dramatic visual width and a pronounced ground-hugging forward presence — a comprehensive front-end transformation rather than a subtle trim addition.
Build
- Material: Genuine carbon fiber, manufactured for precise lip geometry, consistent panel surface, and an authentic weave appearance over carbon-look ABS or fiberglass alternatives
- Surface finish: High-gloss epoxy-polished and UV-protected finish that showcases the natural carbon weave and resists UV exposure, moisture, and road debris through sustained outdoor and driving use
- Configuration: Single-piece full-width diffuser lip for the lower front bumper
- Panel width: 180 cm across
Design & Finish
- Aggressive stance: Lip profile adds visual width and a lower, ground-hugging forward presence for a more commanding, track-inspired front end
- Full-width coverage: The 180 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 sporty S-Line and S5 bodywork for a coordinated, motorsport-grade look
Fitment
- 2017–2019 Audi A5 S-Line (B9)
- 2017–2019 Audi S5 (B9)
- Fits the A5 S-Line and S5 factory front bumper only — not compatible with the standard non-S-Line A5, aftermarket bumpers, or non-B9 configurations
- Confirm your body style and front bumper configuration before ordering
Package Contents
- 1 × carbon fiber front bumper diffuser lip
- Installation hardware
Installation
- Surface prep: Thoroughly clean and degrease the front bumper before installation to ensure correct panel seating and secure fitment
- Alignment: Dry-fit and check the lip sits centred and even across the bumper, with consistent panel gaps on both sides, before final fitting
- Professional installation strongly recommended — a panel of this width requires careful positioning to achieve symmetrical alignment and a clean finish
- Plan for a second pair of hands during fitting given the panel's full-width span
Before You Install
- Confirm your car is an A5 S-Line or S5 B9 (2017–2019) before ordering — this will not fit the standard non-S-Line A5
- Verify your factory front bumper is unmodified before ordering
- Front lips sit low and are exposed to kerbs, driveway ramps, and road debris — take care when parking nose-in
