2013–2016 Audi A5 / S5 8T Facelift Rear Bumper Diffuser – Carbon Fiber
2013–2016 Audi A5 / S5 8T Facelift Rear Bumper Diffuser – Carbon Fiber
Upgrade the lower rear profile of your Audi A5 or S5 8T Facelift with this carbon fiber rear bumper diffuser. Spanning 152 cm for full-width lower coverage, it adds width and visual aggression to the factory rear bumper for a more planted, performance-oriented stance in a deep gloss black carbon finish.
Build
- Material: Genuine carbon fiber, manufactured to precise tolerances for consistent panel quality, high structural integrity, and an authentic weave appearance over carbon-look ABS or fiberglass alternatives
- Surface finish: Deep gloss black finish with a UV-resistant coating 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 for the lower rear bumper
- Panel width & weight: 152 cm across · approximately 4 kg
Design & Aerodynamics
- Aggressive stance: Diffuser profile adds width and visual weight to the lower rear for a more planted, track-inspired rear end
- Full-width coverage: The 152 cm span covers the complete lower rear bumper for an integrated finish with no exposed factory sections
- Carbon aesthetic: Directional weave and gloss black finish complement the factory 8T bodywork for a coordinated, motorsport-grade look
Fitment
- 2013–2016 Audi A5 (8T Facelift)
- 2013–2016 Audi S5 (8T Facelift)
- Facelift 8T only — does not fit the pre-facelift 8T, which uses a different rear bumper profile
- Fits the factory rear bumper only — not compatible with aftermarket bumper configurations
- Not compatible with the later B9 generation A5 / S5
Package Contents
- 1 × carbon fiber rear bumper diffuser
- Installation hardware
Installation
- Surface prep: Thoroughly clean and degrease the rear bumper before installation to ensure correct panel seating and secure fitment
- Alignment: Dry-fit and check the diffuser 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 size and weight requires careful positioning to achieve symmetrical alignment and a clean finish
- Plan for a second pair of hands during fitting given the panel's width and 4 kg weight
Before You Install
- Confirm your car is the 8T facelift, not the pre-facelift model — the pre-facelift rear bumper is a different profile and this diffuser will not fit it; check your build date if you are unsure
- Verify your factory rear bumper is unmodified before ordering
- Take care when parking rear-in — full-width lower rear panels sit close to kerbs and parking blocks

Can I install OEM parts myself, or is it better to have a professional handle it?
While some OEM parts can be installed by DIY enthusiasts, the complexity of installation can vary. For the best results and to ensure proper fitment and performance, we recommend having a trained mechanic install the parts, especially if you’re unfamiliar with automotive repairs.
