2013–2016 Audi A7 S-Line C7 Sportback Rear Bumper Diffuser – Carbon Fiber
Transform the rear profile of your Audi A7 S-Line Sportback with this carbon fiber rear bumper diffuser. A direct-fit retrofit that replaces the factory lower rear valance, it sharpens the rear end with a bold, performance-focused carbon profile that visually widens the rear stance and builds on the A7's S-Line character.
Build
- Material: Genuine carbon fiber — lightweight, durable, and built to withstand long-term driving and outdoor exposure
- Surface finish: Gloss black polished finish that holds its deep carbon appearance and weave clarity without fading or yellowing under prolonged sun and weather exposure
- Configuration: Single-piece diffuser for the lower rear bumper
- Colour match: Gloss black carbon integrates cleanly with both light and dark factory paint colours
Design & Aerodynamics
- Aggressive stance: Diffuser profile visually lowers and widens the rear stance for a more track-inspired, performance-focused rear end
- Carbon aesthetic: Consistent directional weave and gloss finish complement the sporty contours of the A7 Sportback for a coordinated, motorsport-grade look
- Factory-style integration: Precision-molded to the contours of the factory rear bumper for a clean, seamless fit
Fitment
- 2013–2016 Audi A7 S-Line Sportback (C7, 4-door)
- Fits the A7 S-Line factory rear bumper only — not compatible with the standard non-S-Line A7 or aftermarket rear bumper configurations
- Body style: Sportback (4-door) only
- Confirm S-Line trim as well as model year before ordering
Package Contents
- 1 × carbon fiber rear bumper diffuser
- Protective carton packaging
Installation
- Bolt-on retrofit: Replaces the factory lower rear valance — no cutting or permanent bodywork modification required
- Surface prep: Thoroughly clean and degrease the rear bumper before installation for a secure, precise fit
- Alignment: Check that the diffuser sits centred and even across the rear bumper before final tightening
- Professional installation recommended for the best alignment, panel-gap consistency, and finish
Before You Install
- Confirm your car is an A7 S-Line Sportback (2013–2016) before ordering — this will not fit the standard non-S-Line A7
- Mounting hardware is not included — this is a bolt-on part, so source any required fasteners or clips ahead of installation
- Installation is reversible with correct technique, preserving the factory valance for future reinstallation
- Verify body style and trim using your model year if you are unsure
K2 Industries & OUR OWN FAQ's
How do I check fitment?
Check the listing for your year, make, model, trim and engine. Body style, build date and factory options can matter. If the listing is unclear, send FI Performance your vehicle details and the product link or SKU before ordering.
What comes with this part?
Check the product description for quantities, hardware and accessories. Photos may show the part installed with other components. Ask us if you need to confirm whether a part is sold individually, as a pair or as a kit.
Will I need extra parts or modifications?
That depends on the part and your setup. Check for adapters, wiring, coding, tuning, trimming or additional hardware before booking installation. If you already have aftermarket parts, tell us what’s installed.
What should I check for headlights or tail lights?
Match your factory lighting type, connector and body style. Halogen, HID and LED assemblies can differ even on the same model. Check pre-facelift versus facelift fitment and features such as adaptive lights or leveling.
Should I have a shop install it?
We recommend a qualified installer for wiring, engine, brake and suspension work. Inspect the part and confirm fitment before cutting, drilling, painting or modifying anything.
When will my order ship?
Availability and lead time vary by item. If you’re working around a shop appointment or event, contact FI Performance for a current estimate before ordering.
How do returns and warranty claims work?
Contact FI Performance with your order number before sending anything back. Eligibility depends on the item, its condition and the applicable policy. If there’s damage or a defect, keep the packaging and send photos of the part, label and issue.
Is this part intended for street use?
Check the listing for any use restrictions and confirm the requirements where you drive. If you need a specific approval or certification, ask us to verify it for the exact part number before ordering.
