BMW G80/G81 M3 & G82/G83 M4 Gloss Black Rear Diffuser With LED

This gloss black rear diffuser with integrated LED for the BMW G80/G81 M3 and G82/G83 M4 is a striking exterior upgrade designed specifically for models equipped with the factory M3 and M4 rear bumper. Styled in an F1-inspired layout, it adds visual depth and modern detail to the rear of the car while maintaining a clean, cohesive appearance.

Manufactured from high-quality ABS plastic, the diffuser offers excellent durability for everyday road use and a smooth, painted gloss black finish that complements factory trim and other exterior accents. The integrated LED centre light adds a distinctive finishing touch, giving the rear end a more purposeful and contemporary look without appearing excessive or out of place.

Designed for precise fitment, this diffuser follows the contours of the M3 and M4 bumper closely, ensuring it integrates naturally with the rear profile of the car. It’s an ideal upgrade for owners looking to enhance rear-end styling with a feature-led design that still delivers strong value and reliable fitment.
