Dinan High Flow Air Intake System

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. While the stock intake system is adequately suited to support up to stage 1 power levels that does not mean there is no performance benefit when upgrading to the Dinan system. Besides its amazing appearance the biggest advantage of the system, by virtue of additional and optimized flow, is the reduction of the pressure depression in the stock system. This equates to the turbo having to work less in order to achieve targeted power. With the turbo working more efficiently this also means a lower pre-turbine backpressure, lower turbocharger shaft speeds, lower turbocharger compressor discharge temperatures, and for the ability to achieve higher boost pressure levels. Coupled with the optional Dinan Turbo Inlets these effects are even more exacerbated and represent ideal optimum flow and efficiency.
