Gloss Black Rear Diffuser For BMW 4 Series G22 G23 M-Sport (2020-2022)

Want to give the back end of your 2020-2022 BMW 4 Series (G22 or G23 with M-Sport package) a meaner look?

This gloss black rear diffuser is exactly what you need.

It's a direct replacement for the factory piece and made from durable ABS plastic.

The finish is a sleek, painted gloss black that really sets off the lines of the bumper.

It's more than just looks, though—it acts as a protector for your bumper, too.

Fits the 430i and M440i M-Sport models perfectly for the 2020, 2021, and 2022 model years.

Comes with a 1-year warranty and is ready to bolt on.

Makes a huge difference in the rear profile.
