Audi B5 S4 / RS4 V6 Biturbo Carbon Fiber Engine Covers
Transform your engine bay with our custom carbon fiber V6 Biturbo engine covers for the Audi B5 S4 and RS4—designed to deliver a bold OEM+ appearance while showcasing the iconic twin-turbo platform.
As one of the most prominent features in the engine bay, these covers create an immediate visual impact. Whether you’re building a full carbon engine bay or upgrading key components, they add depth, contrast, and a premium motorsport-inspired finish that stands out.
Each set is meticulously hand-crafted in-house using premium 3K 2x2 twill carbon fiber, ensuring a consistent weave pattern that complements OEM styling. Unlike refurbished factory covers or carbon overlays, these are true carbon fiber components built entirely from the ground up—eliminating the common issues associated with factory “carbon-look” finishes.
Engineered for precise fitment, the covers integrate seamlessly with the OEM mounting locations while maintaining proper function and clearance within the engine bay.
Finished with a high-quality UV-resistant clear coat, each piece is designed to maintain long-term clarity and resist yellowing—even under the high temperatures typical of the 2.7T engine bay.
Optional embedded “Bi Turbo” lettering is available, encapsulated beneath the clear for a clean, factory-inspired look.
