Audi R8 4S Carbon Diffuser Rear Bumper

Audi R8 4S Carbon Diffuser Rear Bumper

Product Overview

For sale is a genuine OEM Audi R8 4S carbon fibre rear bumper diffuser — an original Audi manufacturer part specific to the R8 4S (4S0 chassis). This is the carbon diffuser element integrated into the R8 4S rear bumper assembly, providing the model’s signature aerodynamic lower rear treatment in genuine factory carbon fibre — not an aftermarket reproduction.

The R8 4S rear carbon diffuser is a visually prominent and aerodynamically functional component that defines the R8’s rear profile. Genuine OEM carbon fibre from Audi’s factory carries a weave quality, lacquer depth, and dimensional accuracy that aftermarket alternatives cannot match, making OEM sourcing the correct choice for any owner undertaking an insurance repair, accident repair, or condition restoration on a car of the R8’s value.

Part Specification

About the Audi R8 4S Rear Carbon Diffuser

The Audi R8 4S was produced across two distinct generations of the second-generation R8 — the original 4S series (2016–2019) and the facelifted 4S series (2020–2023) — each with subtle differences in rear bumper and diffuser geometry. The carbon diffuser is a standard or optional factory fitment depending on the trim level and specification, and represents one of the most visually defining elements of the R8’s rear profile.

The R8’s factory carbon fibre components are produced to the exacting standards of Audi’s manufacturing process — including pre-preg carbon construction, UV-resistant automotive lacquer, and dimensional tolerances set to the same standard as the body panels they are mounted alongside. An OEM carbon diffuser provides a fit, finish, and long-term colour stability that no aftermarket item can guarantee at equivalent cost.

Ideal For

• Audi R8 4S owners requiring a factory-original carbon diffuser following accident damage, kerb contact, or stone chip damage
• R8 and exotic car body shops sourcing a genuine OEM carbon component for an insurance or accident repair
• R8 owners upgrading from a non-carbon rear diffuser to the factory carbon specification
• Insurance repair specialists requiring a genuine OEM part for an R8 rear-end claim
