StealthFlow Inlets by ModalWorks
Unleash the hidden potential of your C190 M178-equipped AMG GT with the ultimate stealth performance upgrade. Engineered by the experts at ModalWorks, the StealthFlow Inlets are crafted from lightweight carbon fiber composite plastic—perfectly matched to your AMG’s factory engine bay and exterior aesthetic. These 4.25" to 3.125" intake tubes blend seamlessly into your setup while delivering jaw-dropping performance gains.

Engineering & Design:

Using cutting-edge Computational Fluid Dynamics (CFD), our team pinpointed the weak link in the factory system: the restrictive plastic inlet at the turbocharger. The StealthFlow Inlets eliminate this bottleneck, replacing the stock plastic inlets and turbo couplers with a sleek, high-efficiency design that flows effortlessly into your original airbox. The result? A stealthy upgrade that looks stock but performs like a beast.

Designed to pair perfectly with ModalWorks’ turbocharger lineup, the StealthFlow Inlets maximize the potential of our 3-inch inlet turbo systems.

Stealthy, powerful, and precise—the StealthFlow Inlets are the upgrade you’ll feel, not flaunt.
