BMW G20 B48/B46 Intake System - Pre 2018 November

Performance

Below is a dyno graph showing the comparison between the Eventuri and the stock airbox on a standard B58 M240i. As you can see, power and torque are increased through a large portion of the rpm range. This translates on the road to increased part throttle and full throttle response with the car pulling much more eagerly to the redline. At peak RPM the power curve for the intake merges with the stock airbox - this is due to the fact that on the dyno, the intake relies on the fan to push air through the scoop and into the filter. At high RPM the fan is simply inadequate in providing the required airflow - on the road this would not be a problem and we would expect the intake to continue making power gains up to the redline. The testing was done on the same day back-to-back and temperatures were monitored to ensure consistency.
