Overview

The M Performance rear diffuser is a genuine replacement part designed to provide an aggressive, matte black aesthetic for your vehicle's rear end. Crafted from high-quality PUR-RIM (polyurethane reaction injected molding), this diffuser follows the natural body lines of the vehicle for a precise, factory-level fit.

Show original supplier description

Constructed using PUR-RIM (polyurethane reaction injected molding) material, this diffuser offers durability and a refined matte black finish. This specific diffuser is compatible with BMW F22 and F23 2-series models, including the M235i, M235i xDrive, M240i, and M240i xDrive, covering both 2014-2020 production years. Please note that exact fitment can vary based on specific trim configurations; we recommend using a vehicle selector tool to confirm compatibility with your exact model. Professional installation is often recommended to ensure proper alignment and retention of the factory-grade fit and finish.
