Dinan Gloss Carbon Fiber Cold Air Intake – 2021-2026 BMW M2/M3/M4

Equal parts function, sound, and beauty, the intake not only looks and sounds the part of something special but performs the part as well. With a 12% increase in airflow to the engine without any negative effects on inlet temperatures or pressure, the Dinan G8x system delivers on all fronts. Drawing in more unimpeded air for consumption yields more efficient turbos (less work to make the same power) with the capacity for greater power potential on modified builds. Central to the design and our obsessive-compulsive need for a symmetrical engine bay is a singular plenum that replaces the separated driver and passenger intake ducting on the stock setup. The combination of the two tracks into one enlarged and distinctive shared pathway allows 50% more volume to be achieved in this tight space in addition to simplifying the installation and improving the overall look. The center plenum gives way to enlarged airboxes that house 11% larger cotton air filters delivering superb filtration while maximizing flow. Feeding the filters are the factory grill inlets as well as additional cutouts on the top of each airbox lid. The semi-open design was analyzed extensively to ensure that these additional inlets had no ill effect on temperatures or flow. However, the secondary airbox passages do allow an avenue for the induction soundtrack to escape the confines of its former plastic prison for everyone’s benefit. Whether under hard acceleration, deceleration, or just spooling the amplified sounds are sure to make an impression.
