Rieger Audi A3 Saloon S-Line (8V) Pre-Facelift (2012-2016) Rear Diffuser
The Rieger rear diffuser is a direct-fit styling upgrade for the Audi A3 S-Line Saloon (8V) pre-facelift models. It replaces the standard lower rear bumper section with a more purposeful, aggressive-looking panel that suits the S-Line aesthetic well.
What a rear diffuser does
A rear diffuser is the shaped panel fitted beneath the rear bumper. As you drive, air flows under the car and exits at the back – the diffuser controls how that air exits, reducing turbulence. This can help reduce drag and improve high-speed stability, while also giving the rear end a cleaner, sportier appearance.
This Rieger diffuser is designed to match the pre-facelift S-Line rear bumper profile and features a twin tailpipe cut-out on the left side, keeping things looking factory-fitted rather than bolted on.
- Sportier, more purposeful look from the rear
- Helps manage airflow beneath the bumper for improved stability
- Twin tailpipe left cut-out to suit common exhaust layouts on these cars
- Manufactured from ABS plastic – lightweight and durable
- Direct replacement fit with mounting hardware included
