Dinan 20-26 BMW X5 M Competition Cold Air Intake

Beyond outward appearances and upon closer inspection details emerge which showcase the level of care taken in the intake systems design beyond simply aesthetics. For instance, the secondary air source is deriving its contents from an unobtrusive central hood scoop located behind the front grilles that feeds into the newly formed inlet hump at the front of the engine bay. Through constant CFD analysis, the design of the scoop and secondary inlet continually underwent improvements in order to meet the demand of an even and un-agitated air supply to each air box. In its final form, accents in the carbon both provided a visual embellishment as well as created the outward manifestations of the runners used to direct and smooth the secondary air flow. The additional air flow ultimately 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 (56% larger than stock) that completely seals allowing an increased volume of air to be utilized.
• 86% increase in inlet cross sectional area via the center inlet/scoop (secondary inlet) for maximum airflow.
• More Flow: 10% greater than stock (Stock: 575 CFM, Dinan: 630 CFM @ 30" H2O per bank).
• 46% increase in filter area (stock: 51in², Dinan: 82in² per side) for optimum flow.
• Center inlet/scoop doubles as a visually pleasing carbon fiber engine cover.
• Increased turbo efficiency, reliability, and head room.
• Increased sound for aural satisfaction at full load.
• Carbon Fiber overload – the good kind.
• Improved throttle response.
• Bolt-on installation.
