This DIY guide is intended to help with the installation of the Agency Power Aeroform Carbon Fiber Rear Diffuser for BMW F82 F80 M4 M3 2015-2016

The following is recommended for installation:

• 3M Automotive Double Side Tape
• 8mm socket/nut driver
• 50:50 isopropyl alcohol and water
• Clean Microfiber towel
• Friend to assist

PLEASE NOTE* Be very careful not over tighten any screws that attach the carbon fiber pieces. You will crack the carbon! This is not covered under warranty!

STEP 1:  Remove the (4) 8mm screws securing the OEM diffuser.

STEP 2:  The OEM diffuser is held in by plastic clips. Carefully pull to free from rear bumper.

STEP 2:  Since we will be using 3m double side tape we will need to prep both the underside of the bumper and the Aerofrom rear diffuser by wiping it down using a 50:50 isopropyl alcohol and water mixture. Make sure to use a clean microfiber to avoid scratching the carbon. After the surfaces are clean apply the 3m double side adhesive to the underside of the bumper. Use the the images below for reference.

STEP 3:  Peel back the 3m tape and with the help of friend carefully line up and attach the Agency Power diffuser to the bumper. Replace the (4) 8mm screws and use the supplied self taping screws to secure the diffuser at the pre-drilled locations.

STEP 5:  Enjoy the new look of your BMW F8X with the Agency Power Aeroform Carbon Diffuser.
