BMW M340i G20 G21 LCI Carbon Fibre Rear Diffuser by Adro (2022+)

BMW G20 M340i / M340d LCI CARBON FIBRE REAR DIFFUSER

Available through AutoID as an official UK distributor, the ADRO rear diffuser for the BMW G20 M340i LCI brings a more sculpted and refined presence to the rear of the vehicle.

Designed to enhance rather than overpower, this diffuser introduces greater depth and definition through its distinctive three-piece construction. The layered design creates a more tailored, architectural look — adding visual complexity while maintaining a clean, OEM+ aesthetic that complements the factory styling.

Crafted from premium wet carbon fibre and hand-finished with exceptional attention to detail, each component delivers a precise fit and high-quality finish. The result is a subtle yet striking upgrade that feels both purposeful and sophisticated.

For a more complete rear-end transformation, this diffuser is fully compatible with ADRO’s G20 M340i LCI Carbon Fibre Rear Winglets, allowing you to build a cohesive and well-balanced look.
