Triple R Composites Audi S5 B9 Coupe Set of 4 Diffuser Fins
Give your Audi S5 B9 Coupe a sharper, more purposeful rear end with this set of 4 diffuser fins. They add a clean, motorsport-inspired look that suits the factory bumper without being over the top.
Each fin sits neatly on the lower rear bumper to break up the flat area and create a more aggressive style. The design helps guide air as it leaves the rear of the car, which can reduce drag slightly and make the back of the car look wider and lower on the road.
- Subtle but noticeable styling upgrade for the rear bumper
- Gives a wider, lower and more performance-focused look
- Made from tough Nylon 12 for strength and impact resistance
- SLS 3D printed for accurate fit to the S5 B9 Coupe bumper
- Media blasted and coloured black for a smooth, OEM-style finish
- Supplied with stainless steel fitting kit for a secure install
Construction and finish
These diffuser fins are manufactured in Nylon 12 using an SLS 3D printer. SLS (Selective Laser Sintering) uses a laser to fuse nylon powder into a solid part, giving strong, light components that match the bumper shape closely.
After printing, the fins are media blasted for a uniform surface and coloured black. This gives a neat, factory-like appearance that blends well with OEM trim and most aftermarket rear diffusers.
Fitment and compatibility
Designed specifically to fit Audi S5 B9 Coupe models from 2016-2019. They are intended to mount on the standard rear bumper and work alongside most OEM or mild aftermarket exhaust set-ups.
Please check any existing rear diffusers or aftermarket bumpers for clearance before drilling or fixing the fins.
Use the vehicle lookup on our site or check the Vehicle Fitment tab for full details before ordering.

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.
