The BMW M5 is the flagship of the marque and deserves only the finest components. The Dinan Carbon Fiber Cold Air Intake lives up to that philosophy, delivering one of the most efficient, highest-performing, and visually stunning sealed intake systems available for the BMW M5 F90.

The first thing you notice when opening the hood is the sheer presence of gloss UV-coated 2x2 carbon fiber stretching across the engine bay through a fully functional wishbone secondary inlet. Beyond its dramatic appearance, this component also helps deflect heat while serving as an additional air source.

Unlike the structural brace used in the F8x M3/M4, the wishbone here channels fresh ambient air from a central hood scoop located behind the kidney grilles. This supplementary airflow feeds the enlarged left and right airboxes with cool outside air, working alongside the factory inlet locations. Combined with massive filters, the system maximizes intake efficiency and airflow potential.

Greater Turbo Efficiency & Real Performance Gains

While the factory intake system adequately supports Stage 1 power levels, the Dinan system delivers measurable benefits through increased and optimized airflow. Its biggest advantage is the reduction of intake pressure depression, meaning the turbochargers work less to achieve target power levels.

Benefits include:

• Increased turbo efficiency
• Lower pre-turbine backpressure
• Lower turbo shaft speeds
• Reduced compressor discharge temperatures
• Greater boost potential
• Improved throttle response
• Slightly more aggressive intake sound

When paired with optional Dinan Turbo Inlets, the system reaches its maximum flow and efficiency potential.
