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.Key Features: Replaces OEM BMW part numbers 51118084935 & 51118084936 Pre-preg carbon fiber construction — autoclave cured Direct replacement for factory gloss black plastic air curtains Matches carbon fiber center bumper trim and front lip Completes a full...

Product Info



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.

Key Features:

  • Replaces OEM BMW part numbers 51118084935 & 51118084936
  • Pre-preg carbon fiber construction — autoclave cured
  • Direct replacement for factory gloss black plastic air curtains
  • Matches carbon fiber center bumper trim and front lip
  • Completes a full carbon fiber front end build
  • Sold as a complete set (left and right)

What's Included:

  • 1x Left side front bumper air curtain (carbon fiber)
  • 1x Right side front bumper air curtain (carbon fiber)

Replaces OEM Part Numbers:

  • 51118084935 (Left)
  • 51118084936 (Right)

Fitment:

  • BMW M5 Sedan (G90)
  • BMW M5 Touring (G99)


Installation Note: The front bumper must be removed to access and install the air curtains. Professional installation recommended. Ensure all mounting surfaces are clean and free of debris prior to installation.
