This is our flagship Pre-Preg Dry Carbon Fiber Diffuser for the F87 M2 and F87 M2 Competition. We designed this diffuser to mount directly into the lower rear factory bumper for a fast and straightforward installation. This true carbon fiber diffuser is made with our 100% pre-preg technology for the ultimate lightweight, high-durability, and precise fitment. AutoTecknic Pre-Preg Dry Carbon Fiber Diffuser is both highly visible and highly functional.

Dry carbon fiber's name comes from its manufacturing process. Dry carbon fiber is formed using a "pre-preg" or impregnated piece of carbon materials. This piece of carbon is first placed into a mold and then into a sealed autoclave to properly cure. This method creates the least amount of waste and forms a lighter version of carbon than the "wet" method. The autoclave vacuuming process of making dry carbon means fewer pinholes and virtually no air pockets that form in the carbon. Dry carbon is the highest-quality version of carbon fiber products that are produced.
