This BMW G8X M3/M4 OEM Style Forged Carbon Diffuser offers a new spin on our regular CF diffusers for the M3 or M4. Forged Carbon is created through a different process that provides a product with a more distinct and bespoke look. We know our customers care deeply about the parts they choose to install on their vehicles which is why we only use the highest quality carbon material, clear coats, and resin in the making of our products. Just like the rest of our product line, this OEM Style Forged Carbon Diffuser comes with the RW superior fitment and quality guarantee. Installation is purely bolt-on and does not require any special modifications or cutting.
