Dinan - D760-0049 - Dinan Cold Air Intake - 2018-2023 BMW M5

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."
