Audi A4/S4 B9/9.5 (2016 - 2023)
The B9 generation brought a sharper design, lighter chassis, and advanced technology across the A4, A5, and their performance S and RS models. In 2020, the facelifted B9.5 introduced refreshed styling, upgraded lighting, and updated infotainment. From daily drivers to high-performance S and RS variants, these models feature the popular EA888 engines, quattro drivetrains, and refined interiors—making them some of the most versatile and tunable Audis on the market.
Explore our range of genuine and performance parts to keep your B9 or B9.5 running strong, whether it’s for maintenance, styling, or pushing the limits of power.
