Cold Air Intake System - Carbon Fiber

The Dinan Carbon Fiber Cold Air intake for the latest generation of BMW M5 (F90) models from 2018 to 2021 is a true testament to the brand's commitment to offering the best possible components for its flagship vehicle. Sold as a kit, this intake system holds true to Dinan's philosophy of delivering the most visually impressive and high-performing solutions on the market.

The first thing that catches the eye when gazing upon the engine bay equipped with the Dinan intake is the sheer amount of gloss UV-coated 2x2 carbon fiber, stretching from one end of the engine compartment to the other. This material not only serves the purpose of heat deflection but also adds to the overall aesthetic appeal of the engine bay.

The secondary air inlet wishbone, which mimics the equally impressive design of the F8x M3/M4 engine compartment, serves a different purpose. Instead of adding structural integrity, the wishbone acts as a conduit for a secondary air source, deriving its contents from a central hood scoop located behind the front grilles. This additional air flow supplements the factory inlet locations on both the left and right air boxes, providing the intake system with a higher volume of ambient air from outside the engine compartment.

The air boxes have been enlarged and equipped with massive filters to handle this increased volume, and together with the rest of the system, the Dinan intake allows for efficient and optimized airflow. While the stock intake system is adequate for supporting up to stage 1 power levels, upgrading to the Dinan system offers a significant performance benefit.

The biggest advantage of the Dinan intake system is the reduction in pressure depression within the stock system. This means the turbo has to work less to achieve the targeted power, resulting in increased turbo efficiency, reliability, and headroom. In fact, the Dinan intake boasts an 11% greater flow than the stock system, with a CFM of 637 at 28" H2O per bank, compared to the stock's 575 CFM.

The incorporation of the center wishbone inlet/scoop as an additional secondary air source further enhances the system's maximum airflow capabilities. The larger volume air boxes, which are 31% larger than the stock units, also contribute to the increased air utilization, as they completely seal the system, allowing for more efficient airflow.

The performance improvements offered by the Dinan Carbon Fiber Cold Air intake are not limited to just numbers. The system also delivers improved throttle response, making the driving experience even more engaging and rewarding. The M5 is the flagship of the BMW marque, and the Dinan intake ensures that this model showcases the best possible components, living up to the brand's philosophy of delivering the ultimate driving experience.
