EVENTURI LÉGSZŰRŐ-BMW E46 M3 KEVLÁR INTAKE

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 optimisation. 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 fibre 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.

Below is a dyno graph showing the comparison between the Eventuri and the stock airbox on a standard car with just a rear exhaust and standard map. As you can see, power and torque are increased through a large portion of the rpm range not just at the peak. This translates on the road to increased part throttle and full throttle response with the car pulling much more eagerly to the redline. The testing was done on the same day back-to-back and temperatures were monitored to ensure consistency.


Although the Eventuri system does not require a remap – we have seen further gains when the E46 M3 is subsequently remapped. The graph below shows another E46 M3 with 3 curves – stock, Eventuri and then Eventuri with a remap. In this instance the car was remapped by Evolve Automotive.
