The M5 stands proudly as the flagship of its brand, and it certainly deserves the finest components available. That’s where the Dinan Carbon Fiber Cold Air Intake comes in for the latest generation of M5. This intake not only follows that philosophy but also presents what many consider to be the best-performing and most efficient sealed intake solution on the market. Plus, it’s quite a sight to behold!

As you take a moment to admire the engine bay fitted with the Dinan intake, you can’t help but notice the stunning gloss UV-coated 2x2 carbon fiber that stretches from one end of the engine compartment to the other. Thanks to a fully functional secondary air inlet wishbone, this material is not just eye-catching; it also plays a role in heat deflection. The wishbone, which echoes the striking design of the F8x M3/M4 engine compartment, serves a unique purpose. Rather than simply adding structural integrity, it channels a secondary air source from a central hood scoop located behind the front grilles. This extra airflow enhances the factory inlet locations on both the left and right air boxes, pulling in ambient air from outside the engine compartment. These air boxes have been enlarged and fitted with massive filters to accommodate this increased airflow, allowing the intake to operate as efficiently as possible.

While the stock intake system is more than capable of supporting up to stage 1 power levels, upgrading to the Dinan system brings its own set of performance benefits. Beyond its stunning appearance, the standout feature of this system is its ability to optimize airflow, resulting in reduced pressure depression in the stock setup. This means the turbo doesn’t have to work as hard to achieve your desired power. With the turbo operating more efficiently, you can expect lower pre-turbine backpressure, reduced turbocharger shaft speeds, and cooler compressor discharge temperatures, all while achieving higher boost pressure levels. When paired with the optional Dinan Turbo Inlets, these enhancements are amplified, creating an ideal flow and efficiency. You’ll also notice a natural improvement in throttle response, a subtle boost in acoustics, and a visual appeal that will leave onlookers speechless. The Dinan F90 M5 carbon fiber intake system truly complements the "best."
