BMW M340i G20 G21 LCI Carbon Fibre Rear Diffuser by Adro (2022+)
ADRO Carbon Fibre Rear Diffuser for BMW M340i G20/G21 LCI (2022+)
Available through AUTOID as an official UK ADRO 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 natural shadow lines and visual separation, giving the rear bumper a purposeful, performance-oriented finish that reads cleanly with the LCI's updated body lines.
Constructed from high-quality carbon fibre with a consistent gloss finish, the diffuser is shaped to integrate seamlessly with the LCI rear bumper architecture. All mounting uses existing points | no cutting, drilling or modification required. The design works cohesively with standard and aftermarket exhaust setups.
Key Features:
- Three-piece carbon fibre construction with high-gloss finish
- Designed specifically for the G20/G21 LCI rear bumper (2022+)
- Integrates with the LCI's updated body lines for an OEM+ result
- Direct bolt-on to existing rear bumper mounting points
- Compatible with standard and aftermarket exhaust configurations
- AUTOID is an authorised UK ADRO distributor

FAQs
Q: Does this diffuser fit the pre-LCI G20/G21 (2018–2022)?
A: No. This diffuser is designed specifically for the LCI G20/G21 (2022+), which has a revised rear bumper profile. It is not compatible with the pre-LCI model. AUTOID also stocks the ADRO pre-LCI rear diffuser separately.
Q: Does it fit both the M340i saloon and Touring?
A: Yes. The G20 saloon and G21 Touring share the same rear bumper architecture for the LCI and this diffuser fits both body styles.
Q: Will this work with my aftermarket exhaust?
A: The diffuser is designed around the standard exhaust exit positions. Most aftermarket systems with similar tip placement will work cleanly | contact us with your exhaust setup if unsure.
Q: Can AUTOID fit this?
A: Yes. Fitting is available at our Brentwood, Essex facility. Contact [email protected] to book.
