F97/F98 X3M/X4M (LCI)
4 products
Carbon fiber parts for the facelifted BMW X3 M and X4 M (F97/F98 LCI, 2022 model year on). The range covers front splitters, air vent trims, side skirts, rear diffusers and a vented hood, and the front-end parts are made for the LCI bumper, which is shaped differently from the 2020–2021 cars.
Our own LCI front splitter was designed in-house from a 3D scan of the car and comes with pre-drilled mounting holes and hardware. Alongside it are our X3 M rear spoiler, side skirt extensions and 3-piece diffuser, plus SQ-style lips, canards and diffusers, including X4 M diffusers with and without a brake light. Parts come with a 1-year warranty and our fitment guarantee.
BMW F97/F98 X3M/X4M (LCI) buying guide
LCI or pre-LCI? Check before you order
BMW facelifted the X3 M and X4 M for the 2022 model year. The LCI has a reshaped front bumper with L-shaped corner intakes, slimmer headlights and new taillights; inside, it has a larger 12.3-inch center screen and the gear selector from the M3. Front splitters, lips, canards and vent trims are cut for one bumper or the other, so a pre-LCI splitter won't fit a 2022-on car. If your car is a 2020 or 2021 model, use the X3M/X4M pre-LCI page instead.
Unit 17 designs for the X3 M and X4 M
We developed our LCI front splitter from a 3D scan of the car in our shop, and it ships with pre-drilled holes, self-tapping screws and the installation hardware. The side skirt extensions fit LCI and pre-LCI cars and stop just before the factory underglow light, so it keeps working. The rear spoiler fits the X3 M only, pre-LCI or LCI; it isn't made for the X4 M or a non-M X3. The 3-piece diffuser with rear corner splitters is also an X3 M part. For more on why owners start at the front, read our X3M/X4M splitter article.
X3 M or X4 M?
Most front and side parts are listed for both the X3 M and the X4 M. The rear is a different story: the X4 M's sloping tailgate and rear bumper need their own spoiler and diffusers, so make sure a rear part names your model. The SQ-style X4 M diffuser comes with or without an integrated brake light. See all LCI rear diffusers.
Fitting and finish
Most parts here are pre-preg dry carbon with a UV-resistant gloss clear coat. Some mount on factory points, others with screws or 3M tape, and the SQ-style air inlets need the front bumper removed. The vented hood fits LCI and pre-LCI cars. As with any aftermarket carbon hood, have a professional fit it and expect minor adjustment. Test-fit every part before you paint or install it.
