BMW M140i & M135i F20 F21 LCI Carbon Fibre Performance Rear Diffuser by FORM (2015-2019)
A carbon fibre performance rear diffuser for the F20 and F21 M140i and M135i LCI — the definition the back of the car should have had from the factory. It sharpens the lower rear valance and frames the exhaust properly, with a V-weave centre section of the kind more usually found on supercars.
Key Features
- CFRP construction with a 2x2 weave and symmetrical V/herringbone twill centre
- Adds genuine definition to the diffuser area and showcases the exhaust
- Direct replacement for the OEM diffuser using the factory fixings
- Fits in around 10 minutes with basic tools
- Part of the wider AUTOID BMW carbon range
Compatible Models
- BMW M135i (2015-2017, F20 LCI)
- BMW M135i (2015-2017, F21 LCI)
- BMW M140i (2015-2019, F20)
- BMW M140i (2015-2019, F21)
What's in the Box
- 1 x Carbon fibre (CFRP, 2x2 weave with V/herringbone twill centre) performance rear diffuser
How to Install
Installation takes approximately 10 minutes. The OEM diffuser is held at each end by one removable plastic rivet and one 8mm hexagon bolt — two push rivets and two bolts in total. Remove both, unclip the old diffuser and pull it out. Transfer the reflectors from the original diffuser to the new one, then refit in reverse order.
Fitting is also available at AUTOID HQ — contact [email protected] to make an appointment.
