Audi B5 S4 Carbon Fiber Airbox Cover
Refine your engine bay with our custom carbon fiber airbox cover for the Audi B5 S4—designed to deliver a clean OEM+ appearance while adding a high-end performance aesthetic.
This piece replaces the factory airbox lid with a fully hand-crafted carbon fiber version, instantly elevating one of the most visible areas of the engine bay. It pairs perfectly with additional carbon components or stands out as a subtle centerpiece on its own.
Each airbox cover is meticulously built in-house using premium 3K 2x2 twill carbon fiber, ensuring a consistent weave pattern that complements OEM styling. Unlike refurbished or overlaid factory parts, this is a true carbon fiber component made from the ground up—offering superior quality, strength, and long-term durability.
Engineered for precise fitment, the cover integrates seamlessly with the OEM airbox, retaining proper function while enhancing overall appearance.
Finished with a high-quality UV-resistant clear coat, this piece is designed to maintain long-term clarity and resist yellowing, even in high-heat engine bay environments.
