Price range: £289.93 through £322.88
Rieger Audi RS3 (8Y) Pre-Facelift (2021-2024) Rear Diffuser
The Rieger rear diffuser is a direct-fit styling upgrade designed specifically for the Audi RS3 Saloon and Sportback (8Y) in pre-facelift form, covering models built between 2021 and 2024. It replaces the lower rear bumper section with a more purposeful, well-finished panel that complements the RS3’s aggressive factory styling without looking out of place.
What a rear diffuser does
A rear diffuser is the shaped panel fitted beneath the rear bumper. As you drive, air travels under the car and exits at the rear – the diffuser controls how that air leaves, helping to reduce turbulence behind the vehicle. This can contribute to reduced drag and improved stability at higher speeds, while also giving the rear end a cleaner, sportier appearance that looks purposeful rather than purely decorative.
Rieger is a well-regarded German aerodynamic and styling brand, known for producing parts that fit correctly and finish well. This diffuser is shaped to follow the RS3 (8Y) pre-facelift rear bumper profile closely, so it integrates neatly with the existing bodywork rather than sitting awkwardly beneath it.
- Sportier, more aggressive look at the rear of the vehicle
- Helps manage airflow beneath the bumper for improved stability
- Designed to suit the exhaust layout of the RS3 (8Y)
- Manufactured from ABS plastic – lightweight, durable and easy to paint if required
- Direct replacement fit for the pre-facelift rear bumper
Finish options
ABS Gloss Black (SKU: 00088472) – Supplied in a ready-to-fit gloss black finish. If you want a clean, smart result without any additional preparation or painting, this is the straightforward choice. No paintwork required before fitting.
ABS Satin Black – Requires Painting and Finishing (SKU: 00056851) – Supplied in a satin black primer-ready finish. This option is not finished and must be professionally painted by a competent body shop before fitting. It is intended for those who want to colour-match the diffuser to their bodywork or have it finished in a specific shade. Do not fit this option unpainted, as the surface finish is not suitable for direct use.
Fitment
This diffuser is designed specifically for the Audi RS3 (8Y) pre-facelift, covering models produced from 2021 to 2024. It is shaped to suit the pre-facelift rear bumper and is not suitable for facelift models or other body styles.

In the words of the Vehicle Standards Agency (VCA), type approval provides "confirmation that production and samples of a design will meet specified performance standards".
For emissions components this encompasses noise, emissions and balanced back pressure, which have a strong influence on maintaining engine performance (power), and fuel efficiency. Type approval ensures that an aftermarket component will reach, or exceed the performance standard of the corresponding OE part.
Type-approval then, is a certain guarantee that an end user will receive a product of OE equivalent performance attributes.
Products on the Progressive Parts website that meet this approval will be clearly marked or labelled EC or ECE approved.
