The rear end just got serious.
Give your G20 LCI that proper Competition-style look with this aggressive rear diffuser featuring an integrated LED brake light and deep gloss black finish.
Sharp diffuser fins, a lower-looking rear profile and that centre LED brake light give the back of the car a proper motorsport-inspired vibe — without making it look overdone.
Vehicle Compatibility
BMW G20 LCI — 2023+
- G20 340i: Plug & play installation with the correct rear bumper setup.
- Other G20 models: Requires the compatible 340i-style rear bumper plastic to be changed before installation.
- Suitable for compatible dual-tip exhaust configurations.
Why It Hits Different
Competition-Style Design
Aggressive fins and sharp lines give the rear bumper a more planted and performance-focused appearance.
Integrated LED Brake Light
The centre LED brake light adds that race-inspired touch and makes the rear stand out even more.
Plug & Play for G20 340i
For the G20 340i, the diffuser is designed for a straightforward installation with the included wiring setup. The LED brake light connects using the supplied plug-and-play harness, so no cutting, soldering or major electrical conversion work is required.
Other G20 Models
For other G20 models, the factory rear bumper plastic section will need to be changed to the compatible 340i-style rear bumper plastic before fitting the diffuser. Once the correct plastic is installed, the diffuser and dual-tip setup can be fitted without major conversion work.
Gloss Black Finish
Finished in a deep gloss black that works perfectly with Shadowline trim, black accents and other exterior styling parts.
Lower & More Aggressive Look
The Competition-style design adds more depth to the rear and gives the car a wider, lower visual stance.
