The factory front bumper on the G90 M5 and G99 M5 Touring already has the right bones — the AutoTecknic Carbon Fiber Front Bumper Air Curtain Set just finishes the job. These carbon fiber replacements slot directly into the two side bumper vents, swapping out the OEM gloss black plastic units for a cohesive, purposeful carbon fiber finish that ties the entire front end together.
For owners running a carbon fiber front lip or center bumper trim, the OEM gloss black air curtains have always been the weak link in an otherwise clean front end build. This set closes that gap — matching the weave, finish, and character of the surrounding carbon fiber components for a front bumper that looks like it was designed that way from the start.
Built using AutoTecknic's signature pre-preg carbon fiber process, each piece is autoclave-cured for consistent weave alignment, lightweight construction, and long-term structural integrity. The result is a factory-fit replacement that looks significantly better than what it replaces.
