Technical description and compatibility

AMG diffuser for Mercedes CLA C117 (2016-2018)

Gloss black rear diffuser designed to replicate the look of the Aerodynamics Package on the facelift Mercedes CLA 45 C117 (2016–2018). Made from impact-resistant, weather-resistant thermoplastic ABS, it is lightweight while maintaining good exterior durability. Installation requires drilling the bumper and screw mounting; performing a dry fit before final installation allows the element to be perfectly adjusted. The diffuser comes with the necessary mounting hardware (screws) and may sometimes require paint touch-ups for a factory-integrated look. Suitable for owners looking to enhance the sporty appearance without mechanical modifications; technical support is available if you have any doubts about compatibility. To complete the aerodynamic style, view the collection of fins and splitters on becquet-voiture.com: becquet-voiture.com - Bumper Fins. Order now to complete the AMG look and benefit from dedicated after-sales support.

  3. Mark and drill

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