Engineered from the outset to deliver on our promise on individuality and quality, our rear diffuser for the M140i (and M135i LCI) is what the car needed from the factory. It sets off the back end of the car and adds real definition to the diffuser area - great to showcase your exhaust system.

The standout feature of the carbon fiber diffuser is the unique V-weave in the center. This is commonly found on supercars and emphasises quality and precision.

What's in the box

• 1 x FORM Industries Carbon fiber (CFRP, 2x2 Weave with symmetrical V Twill) Rear Diffuser

Installation

Installation takes approximately 10 minutes. On each end of the OEM diffuser, it's attached underneath by one removable plastic rivet and one 8mm hexagon bolt. Two rivets and two bolts in total. Remove both and unclip the old diffuser - it will pull out. Remove the reflectors from the original diffuser and fit to your new FORM Industries Carbon fiber Diffuser. Begin the process in reverse.

A video tutorial will be coming soon.

Alternatively, we can fit onsite. Please contact us at sales@FORM Industries.co in order to make an appointment.
