Frequently asked questions
How do I know if my G20/G21 is pre-LCI or LCI?

The pre-LCI G20/G21 covers build dates from late 2018 to approximately mid-2022. The LCI facelift was introduced in mid-2022 and can be identified by revised headlight clusters, a restyled lower front bumper and updated rear bumper detailing. The simplest check is your BMW's build date plate (found inside the driver's door frame) - if it reads before mid-2022, your car is most likely pre-LCI. Contact our team if you are unsure.
Does the AUTOID carbon competition front splitter fit the G20 M Sport and M340i?

Yes. The AUTOID carbon competition front splitter is confirmed for the G20 saloon and G21 Touring in both M Sport and M340i specification - all require the M Sport front bumper, which is standard on the M340i and available as a factory option on M Sport 3 Series variants.
What ADRO products are available for the G20/G21 pre-LCI?

AUTOID is an official ADRO distributor. For the G20/G21 pre-LCI, we stock the ADRO carbon rear diffuser as part of ADRO's full carbon programme for the M340i (which also includes a front splitter, side skirts and rear spoiler). Contact us for a full programme quote.
Is the Milltek exhaust for the G20/G21 available for both OPF and non-OPF models?

The Milltek system for the G20/G21 M340i in this range is specifically designed for OPF/GPF-equipped models (the most common configuration from 2019 onwards). It is ECE approved for road use and does not remove the OPF/GPF. An OPF delete variant is also available for off-road and track use only.

BMW G20 / G21 3 Series (2018–2022) Pre-LCI Parts & Accessories

The BMW G20 saloon and G21 Touring represent the seventh generation of the 3 Series - a car that set the benchmark for the executive saloon class with precise, rear-wheel drive handling dynamics, exceptional engine options and interior quality that challenged vehicles in the class above. This collection covers the pre-LCI G20/G21 (2018–2022 build dates) with a comprehensive range of performance upgrades, carbon fibre exterior parts, suspension solutions and exhaust systems.

At AUTOID, our G20/G21 pre-LCI range has been carefully curated for the specific bumper and body panel geometry of the 2018–2022 chassis. Key products include the AUTOID Competition Carbon Front Splitter, ADRO Carbon Rear Diffuser, AUTOID Gloss Black Mirror Covers, Milltek Sport M340i Exhaust System and Eibach Pro-Kit lowering springs - all confirmed fitments for the pre-LCI model.

It is important to note that the 2022+ G20/G21 LCI facelift introduced revised front and rear bumper profiles. Products designed for the pre-LCI (2018–2022) are not always compatible with the LCI model and vice versa. If your car was built in 2022, please check your build date carefully or contact our team to confirm your exact specification.

Key Product Areas:

  • AUTOID carbon fibre competition front splitter (pre-LCI specific)
  • ADRO carbon rear diffuser - 2x2 weave, OEM M Performance quality
  • AUTOID gloss black mirror covers (G20/G21/G22/G23/G26)
