BMW F90 M5 Pre-Preg. Real Carbon Fiber Closed-Box Cold Air Intake System – Genuine Lightweight Carbon and High-Flow Design | F90 Sedan M5 Models – S63 V8 4.4L Twin Turbo (2023+)

Transform the way your BMW F90 M5 breathes, performs, and sounds with the BAVMODS® Pre-Preg Real Carbon Fiber Closed-Box Cold Air Intake System — a cutting-edge upgrade engineered to enhance the power and precision of the S63 4.4L Twin-Turbo V8.

Each intake system is constructed using autoclave-cured pre-preg carbon fiber, the same aerospace-grade process used in modern motorsport applications. This results in a component that is exceptionally strong, ultra-lightweight, and thermally resistant, offering both functional and aesthetic superiority under the hood.

The dual closed-box design isolates the air filters within fully sealed carbon chambers, effectively shielding them from the radiant heat of the engine bay. Cold, dense air is drawn in directly through the factory air ducts, feeding both turbochargers with an uninterrupted, high-volume airflow. The result is a tight vacuum seal that prevents heat soak, stabilizes intake temperatures, and allows the S63 engine to operate at peak efficiency under boost.

Internally, each airbox and connecting duct is CFD-optimized to minimize turbulence and maintain consistent air velocity throughout the intake path. This not only sharpens throttle response but also improves midrange torque and high-RPM breathing. The closed-box design produces a refined, yet powerful induction tone, balancing aggression and sophistication — just like the F90 M5 itself.

Hand-finished in a deep, UV-protected gloss, the weave alignment of the carbon fiber adds a bespoke, motorsport-inspired aesthetic to the engine bay, making this system a true OEM+ upgrade worthy of the modern M flagship.
