bridge the gap
Complete the airflow path between your wheel well and fender vents with BTI's Prepreg Carbon Fiber AC Ducts.
Designed specifically for the 2020–2022 GT500, the duct was engineered to clear the passenger-side Transmission Control Module (TCM). Because the TCM is sensitive to water intrusion, the BTI AC Duct also provides an added layer of protection by shielding the module from water and road debris.
Finish the job and get the most from your fender vents with BTI's Prepreg Carbon Fiber AC Ducts.
Without a duct: Turbulence
Without a duct, air entering the wheel well has no direct route to the fender vents. While some air will eventually find its way out, much of it becomes trapped inside the fender cavity. The result is turbulent and disorganized airflow that causes drag and lift, with air circulating within the fender or escaping into the engine bay rather than efficiently exiting through the vents. This turbulence increases aerodynamic drag and reduces the effectiveness of your fender vents.
with a duct: Efficiency
BTI's AC Duct solves this problem by creating a dedicated airflow path from the wheel well liner directly to the fender vent. By channeling air where it needs to go, the AC Duct maximizes vent efficiency and promotes cleaner, more controlled airflow, reducing drag and producing downforce.
designed in virtual reality
To develop BTI's AC Duct, we began by 3D scanning a GT500 equipped with vented fenders, capturing the complex geometry of the wheel well, fender interior, and all surrounding obstructions. That scan data was then imported into a virtual reality design environment, where we recreated the fender and engineered the duct directly around the vehicle's structure.
This process allowed us to precisely route the duct around obstacles while ensuring it attached exactly where intended. By leveraging advanced scanning and virtual reality design technology, we were able to create a highly complex component that fits as though it were designed by the factory—because, in a sense, it was designed directly within the car itself.
Handcrafted and ultra-lightweight
Wieghs 1 lb
The AC Ducts are 100% prepreg carbon fiber, weighing only approximately 230 grams per side, or 1 pound for the pair.
fitslike OEM
The AC Duct was designed to look and fit as though it were always meant to be there. Every contour and crease in its shape was intentional, carefully engineered to weave around the transmission control unit, cables, and mounting bolts. It connects the fender directly to the wheel liner, creating a dedicated path for air to exit the wheel well efficiently. BTI’s carbon fiber AC Duct is the Missing Link!
Installed, it seamlessly connects the OEM fender liner to the vented fender ducts.

aerospace grade carbon fiber
Not all carbon fiber is the same
ac duct uses prepreg carbon fiber the same that is used in Formula 1 and planes like Airbus A400M, Boeing 787, FA-18 fighter, and the Eurofighter.
Prepreg carbon
Prepreg carbon fiber is the same class of material used in Formula 1 and other top-tier motorsports applications. Prepreg material arrives with a precisely controlled amount of thermoset resin already infused into the fabric—hence the name “prepreg.” This optimized resin-to-fiber ratio produces lighter, stronger, and more consistent components.
Prepreg carbon fiber also delivers two additional benefits: increased heat resistance and greater structural strength.
