Dinan Cold Air Intake for BMW M5 - D760-0049

The M5 is the flagship of the marque and as such deserves to showcase the best possible components. The Dinan Carbon Fiber Cold Air intake for the latest generation of M5 holds true to that philosophy and offers arguably the best performing and most efficient sealed intake solution on the market. Quite possibly the most visually impressive as well. 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. Paired with the natural improvement to throttle response, a minor bump to the acoustics, and a visual appeal that will leave anyone speechless the Dinan F90 M5 carbon fiber intake system is a perfect complement to the "best."

Flow Bench Testing

 

The Dinan intake system, regardless of configuration, outflows and outperforms the factory setup. The base intake system (D760-0049) provides more air flow via an additional inlet, enlarged air boxes/piping and free flowing filters. The upgraded turbo inlets (D760-0053) encourage better efficiency and allow the turbo to breath better by way of increased volume and an organically optimized transition into the turbo that reduces turbulence. A combination of these two elements represents the full Dinan intake system and yields maximum flow potential.

 

Q: I want more. What now?
A: Intake + Inlets. Maximum flow and efficiency.

 

Whether you opted for just the turbo inlets or the base intake system it is highly highly encouraged that you complete the full system to extract maximum benefit out of the Dinan system. The combination of both the base intake system AND the carbon fiber turbo inlets allow the turbochargers to work significantly less for optimum efficiency and more headroom. The combination of the two components also visually completes the under hood appeal with a network of carbon fiber parts that wrap ithemsleves around the engine bay, framing the artwork that is the powerful S63TU, V8 engine. It's a work of art that will surely make any passerbys stop in their tracks and gawk. Don't be ashamed. Be proud. We are.
