Fitting steps

  1. Dry-fit the diffuser

    Place the diffuser under the rear bumper of your BMW 1 Series (F20 or F21, 2011-2018) and check the alignment with the exhaust outlets. Check that the version received matches the "Model" option chosen.

  2. Remove the original part

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

  3. Screw on the diffuser

    Fix the diffuser with the screws on the original mounting points. Tighten gradually, without forcing.

  4. Check the result

    Check the alignment with the exhaust outlets and the clearance from the ground.

  • Put the vehicle on jack stands or a lift: never work under a car held up only by the jack.
  • Let the exhaust cool down before working near it.
