designed to 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, air is turbulent
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, disorganized airflow, 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, the air is organized
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 duct maximizes vent efficiency and promotes cleaner, more controlled airflow.
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.
Constructed from aerospace-grade prepreg carbon fiber, the BTI AC Duct weighs approximately 200 grams. Because it is mounted inside the fender and exposed to water, dust, and road debris, it is supplied in an unpainted finish.
