Transform the rear profile of your Audi A6 S-Line or S6 C7 Avant with this premium carbon fiber rear bumper diffuser lip, precision manufactured using a 3D design and CNC moulding process with full autoclave curing. Designed as a direct-fit retrofit upgrade for the A6 S-Line and S6 Avant factory rear bumper, this diffuser lip introduces a purposeful aerodynamic visual element to the lower rear bumper — visually lowering and widening the rear stance while delivering a more aggressive, motorsport-inspired rear-end presence. Carbon fiber construction offers a superior strength-to-weight ratio, consistent weave pattern, and refined surface quality that perfectly complements the factory Avant bodywork. The high-gloss epoxy polished surface maintains the deep carbon finish over long-term outdoor and driving exposure. Adhesive tape is included for a clean, no-drill installation with no permanent modification required to the factory rear bumper.

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.
