Mercedes-Benz W176 A45 AMG Add-On Rear Diffuser
Give your Mercedes-Benz A-Class a more aggressive rear appearance with this
W176 rear diffuser add-on. Designed for the A45 AMG rear bumper,
this styling upgrade adds larger diffuser fins below the existing rear bumper area for a stronger performance-inspired look.
Unlike a complete replacement diffuser, this is an add-on rear diffuser.
Therefore, it works with the existing rear bumper and diffuser setup rather than replacing the entire lower bumper section.
The gloss black finish also adds extra contrast and complements other black styling accessories.

W176 Add-On Rear Diffuser Fitment
The add-on mounts underneath the existing rear bumper and diffuser area.
First, position all sections and check the spacing across the bumper. Then confirm that the fins sit straight and do not interfere with the exhaust outlets or surrounding components.
Secure mounting is important because the diffuser sits low on the vehicle.
Additional automotive-grade mounting hardware may therefore be required during installation.
Professional installation is recommended for the best alignment and finish.
Important Before Ordering
Please check your rear bumper and existing diffuser shape carefully.
W176 A-Class models use several different bumper designs, so visual confirmation is important before ordering this add-on.
NB. If you are unsure of fit to your vehicle, please contact us before ordering.
