Carbon Fibre Performance Rear Diffuser For BMW M3 & M4 (2014-2020)

• 1 x AUTOID Carbon Fibre (2×2 Weave, CFRP) Performance Rear Diffuser

• BMW M3 (2014-2018, F80)
• BMW M4 (2014-2019, F82 F83)

The OEM diffuser is secured by 2 screws and multiple clips on the upper partition. There are two screws in the centre of the diffuser that must be removed, but are not important to the factory diffuser install. Using the 8mm socket remove all 4 screws
With the screws removed simply pull the diffuser from the bumper. The top clips do not require much pressure so no body tools are required.
With the diffuser removed it is now time for install of the AUTOID carbon fibre diffuser. This piece utilises all 4 8mm screws and the existing body clips. Step 1 of the installation is to line up the clips and carefully press into place.
Now that the diffuser is loosely secured by the mounting tabs simply tighten the four 8mm screws.
