Fitting steps

  1. Dry-fit the diffuser

    Place the diffuser under the rear bumper of your BMW 3 Series (G20 or G21, 2019-2022) and check the alignment with the exhaust outlets. Check the package contents: 1 x gloss black rear diffuser for G20 / G21.

  2. Remove the original part

    Remove the screws and clips under the bumper, then unclip the original skirt or diffuser.

  3. Fit the diffuser
