BMW 4 Series G22 M440i M440d 2020 - 2026 Rear Gloss Black Quad Exit Diffuser

Enhance the rear styling of your BMW 4 Series G22 M440i or M440d Coupe with this M Performance-style quad-exit rear diffuser, designed to provide a more aggressive performance-inspired appearance while complementing the original rear body lines and exhaust layout. Manufactured from ABS and supplied in a glossy black finish, this model-specific rear diffuser is intended for BMW 4 Series G22 M440i and M440d Coupe models from 2020 to 2026. The product title specifically identifies the M440i and M440d applications, so compatibility should not be assumed for other G22 engine variants even where broad vehicle compatibility data appears on eBay. Check your exact rear bumper, exhaust configuration and trim against the supplier images before ordering, and professional installation is recommended.
