BMW M5 (F90) Real Carbon Fiber Dual Closed-Box Cold Air Intake System – Genuine Lightweight Carbon Construction with High-Flow Performance Design | Fits F90 Sedan M5 – S63 V8 4.4L Twin-Turbo (2018–2023+)

Upgrade your BMW F90 M5 with the BAVMODS® Pre-Preg Carbon Fiber Closed-Box Cold Air Intake System — a premium performance upgrade engineered to elevate both form and function. Designed specifically for the S63 4.4L Twin-Turbo V8, this system delivers colder, denser air for improved throttle response, horsepower, and long-term efficiency.

Each intake is constructed from autoclave-cured pre-preg carbon fiber, the same process used in aerospace and motorsport applications. The result is a component that’s exceptionally lightweight, strong, and heat-resistant — ensuring long-term durability with a refined OEM+ finish.

The dual closed-box design seals off the air filters from engine bay heat, feeding both turbos with uninterrupted airflow through factory ducts. By isolating the intake path from radiant heat, it maintains cooler intake air temperatures and prevents heat soak, keeping performance consistent even under heavy load.

Internally, the intake path is CFD-optimized to minimize turbulence and maximize pressure retention. This enhances airflow efficiency, sharpens throttle response, and produces a deep, controlled induction tone that perfectly complements the M5’s twin-turbo character.

Finished in a UV-protected high-gloss clear coat, each carbon piece adds an unmistakably premium aesthetic under the hood — a perfect balance of performance engineering and visual craftsmanship.

Key Features:

• Pre-Preg Carbon Fiber Construction: Autoclave-cured for strength, precision, and minimal weight.
• Closed-Box Dual Intake Design: Shields filters from engine heat for consistent cold air delivery.
• CFD-Optimized Flow Path: Reduces turbulence and maintains stable pressure to both turbos.
• Thermal Heat Resistance: Prevents heat soak for lower, more consistent IATs.
• Dual High-Flow Filters: Washable, reusable, and optimized for maximum airflow.
• OEM+ Fitment: Direct bolt-on design with provisions for factory sensors and ducts.
• UV-Protected Gloss Finish: Deep carbon weave with long-lasting clarity and durability.

Performance Benefits:

• Sharper throttle response and improved turbo spool.
• Increased airflow efficiency and torque throughout the rev range.
• Lower and more stable intake air temperatures.
• Balanced induction sound — aggressive under load, subtle in daily driving.
• Lightweight carbon design that enhances both power and presentation.
