Add depth to the back end of your BMW M3 or M4 with this gloss black V style rear diffuser, which replaces the lower centre section of the rear bumper and adds corner splitters on both sides.
It's cut for the factory quad exit exhaust, so check your exhaust layout before ordering. Cars running an aftermarket system with a different tip arrangement will not line up.
Moulded to the car's own lines for a clean, gap-free fit that sits flush with the factory bodywork.
Professional installation recommended for a precise, flush fit across all three pieces.
