2019-2022 BMW 3 Series (G20) Competition Inspired Carbon Fiber Rear Diffuser

IMPORTANT NOTE FOR CUSTOMERS TRYING TO REPLACE 330 DIFFUSER WITH M340 STYLE: You will need to purchase OEM PART # 51128079607 (rear bracket) as well as the angular exhaust tips in order for the installation to be successful. It is NOT a direct replacement.

Kies Carbon brings you another high quality carbon fiber product for your G20 generation BMW 3 series for the sole purpose of attaining that aggressive stance you've always wanted, without paying the factory price.

The Competition Inspired look provides a very aggressive design with multiple fins to channel air as you enjoy a leisurely cruise or for some spirited driving up in the mountains. The world is at your beckoning!

Kies Carbon aerodynamic upgrades are constructed from industry standard 2x2 weave 3K carbon fiber fabric for a clean look and superb strength. It is also finished with a long lasting, high quality gloss coat finish so your parts will not only look good, but last the test of time.

Note: Please make sure you select the right exhaust option for your particular application.
