Audi A4 S4 B9.5 2020-2025 Gloss Carbon Rear Diffuser With Light
Description
So I’ve got this carbon fiber rear diffuser for my Audi A4/S4 B9.5 — from 2020 to 2025. It’s a Karbel-style one, so it’s got that sharp, aggressive look that fits right in with the car’s sporty vibe.It’s made from a solid, high-quality material — not flimsy or cheap. It holds up well to daily driving, doesn’t scratch or fade, and stays shiny even after years of use. The finish is super glossy, and it really brings out the car’s presence.
It’s not just about looks — it actually helps with aerodynamics. Reduces drag, improves stability, and makes the car feel more planted, especially when driving on the road or on the highway. I can feel the difference in how it handles.
Installation’s pretty straightforward — no cutting, no paint damage. Just fits right into the bumper. I did it myself, and it went smoothly, though I’d say a pro hand would be even better for a perfect fit.
I bought it second-hand, and it’s been sitting in my garage for a while now. It’s not flashy, but it’s a solid upgrade. I’ve got a bit of a budget here — it’s £162 — but I’m not selling it for a lot, just passing it on to someone who’s looking for a real, no-nonsense upgrade.
It’s part of the Penn, Beaconsfield and Chepping Wye Community Board — I’m just passing it along to someone who might actually use it. No fancy fluff, just a real piece that works.
