BMW G82/G83 M4 Dual-Cone Real Carbon Fiber Closed-Box Cold Air Intake System – Genuine Lightweight Carbon and High-Flow Design | G82 Coupe and G83 Convertible M4 and Competition Models – S58 I6 3.0L Twin Turbo (2021+)

Transform the way your BMW G82 M4 or M4 Competition breathes, performs, and sounds with the BAVMODS® Real Carbon Fiber Closed-Box Cold Air Intake System — a next-generation upgrade engineered for the S58 3.0L Twin-Turbo Inline-Six. Designed to deliver precision airflow under extreme pressure, this system enhances throttle response, turbo spool, and cooling efficiency while maintaining an OEM+ sealed enclosure that keeps unwanted heat out and performance in.

Constructed entirely from authentic vacuum-infused carbon fiber, each intake box is hand-laid and heat-cured to perfection, resulting in a structure that is ultra-lightweight, heat-resistant, and visually stunning. The dual closed-box configuration isolates the filters from the radiant engine bay heat, pulling in cold, dense air directly through the factory inlet channels. This creates a true sealed vacuum effect — maintaining consistent air pressure, eliminating heat soak, and delivering cooler intake temperatures for sustained performance across all RPM ranges.

Every component, from the carbon housings to the silicone couplers, is optimized for maximum flow efficiency and minimal turbulence. The dual high-flow cone filters channel air to each turbo independently, reducing lag and creating a smoother, more linear powerband. The closed design keeps intake air temperatures stable, making it ideal for both spirited driving and track conditions.

Finished in a deep, UV-resistant gloss, the carbon weave gives your engine bay a commanding presence — a perfect blend of motorsport aggression and modern luxury that complements the character of the G80 platform.
