The BMW E46 M3 Carbon air intake system is the result of extensive data logging, dyno testing and design optimization. Our goal was to develop an inlet system for the S54 engine that works with the stock ECU card and MAF sensor and has built a real improvement in the driving experience.
With a carbon fabric that matches the OEM M Performance carbon - this is really a new benchmark. The E46 M3 Eventuri system uses their patented Carbon Fiber Housing, which offers an aerodynamically efficient airflow path from the filter to the MAF tube. Not just another cone filter with a heat shield, but a unique design that evokes the Venturi influence.
Having an effective cold air supply to the filters is an essential part of the design. The fact that there are some heat guards in place is not an effective means of preventing heated air from entering the filters unless the shields create an airtight enclosure around the filters. The scoops and channels in our system combine the filter openings with ambient air and ensure a low air temperature.
