BMW E46 M3 Performance increase = 10-15hp, 8-12ft-lb The E46 M3 intake system is a result of extensive data logging, dyno testing and design optimizations. Our aim was to develop an intake system for the S54 engine which worked with the stock ECU map and MAF sensor and produced a genuine improvement in the driving experience. The Eventuri Difference The E46 M3 Eventuri system uses our Patent Pending Carbon fiber Housing which provides 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 which invokes the Venturi affect. You can read more about the housing design and how it works here.
