Fitting steps

  1. Dry-fit the diffuser

    Place the diffuser under your vehicle's rear bumper and check the alignment with the exhaust outlets. Part designed for: Seat Leon 5F and MK3 and Cupra Leon 5F. Check that your vehicle is one of them.

  2. Remove the original part

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

  3. Mark and drill

    Hold the diffuser in place, mark the holes, then drill first with a small bit before the final diameter.

  4. Protect and fix

    Deburr, apply an anti-rust product to the edges of the holes, then fix the diffuser with the hardware and seals.

  5. Check the result

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

  • Check what is behind the panel before drilling (wiring, reinforcements).
  • 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.
