Dinan 18-23 BMW M5 Cold Air Intake

The first thing noticed upon 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, courtesy of a fully functional secondary air inlet wishbone, the material is not only beautiful to look at but serves the purpose of heat deflection as well. The wishbone, which mimics the equally impressive calling card of the F8x M3/M4 engine compartment, is purposeful in a different way. Instead of adding structural integrity, the wishbone serves as the conduit for a secondary air source deriving its contents from a central hood scoop located behind the front grilles. The additional air flow supplements the factory inlet locations on both the left and right air boxes with ambient air from outside of the engine compartment. These air boxes have been enlarged and equipped with massive filters to handle this increased volume and together with the rest of the system allow the intake to flow as efficiently as possible.

• Larger volume air boxes (31% larger than stock) that completely seals allowing an increased volume of air to be utilized.
• Center wishbone inlet/scoop incorporated as an additional secondary air source for maximum airflow.
• 35% increase in filter area (stock: 56.5in², Dinan: 80in² per side) for optimum flow.
• More Flow: 11% greater than stock (Stock: 575 CFM, Dinan: 637 CFM @ 28" H2O per bank).
• Increased turbo efficiency, reliability, and head room.
• Improved throttle response.
• Bolt-on installation.
