G20 M340i LCI M Performance-Style LED Rear Diffuser V2
Upgrade the rear profile of your BMW M340i with our G20 M340i LCI M Performance-Style LED Rear Diffuser V2, featuring a bold full-width design with an integrated vertical LED brake light positioned directly in the centre of the diffuser.
The V2 design features a deep, angular centre section with four prominent vertical diffuser fins, surrounded by large sculpted exhaust openings and extended outer sections that integrate into the LCI rear bumper. The layered upper profile and pronounced lower fins give the M340i a significantly deeper, wider and more aggressive rear appearance.
At the centre sits the defining feature of this design — a slim vertical LED brake light integrated between the diffuser fins. Its straight-line design creates a distinctive illuminated focal point at the centre of the rear bumper while complementing the aggressive geometry of the diffuser.
Available in Gloss Black or Carbon Lookalike.
