Eventuri BMW B58 Carbon Performance Intake (M140i, M240i, 340i & 440i)

The B58 Eventuri intake system is another example of our “Complete System” principal. It demonstrates the perfect balance between allowing for unrestricted airflow with our open filter housing whilst maintaining low IAT by cold air saturation with our scoop and shield combination. Every detail has been meticulously developed from the prepreg carbon pieces to the double layer heat shields. This intake sets a new benchmark in design and craftsmanship for the B58 platform.
The Eventuri Difference
The B58 Eventuri system uses our Patent Pending Carbon fibre Housing which provides an aerodynamically efficient airflow path from the filter to the turbo. Not just another cone filter with a heat shield but a unique design which invokes the Venturi affect and maintains laminar flow conditions to reduce the drag on the turbo. You can read more about the housing design and how it works HERE.
Each intake system consists of:
- Prepreg Carbon Filter Housing and integrated MAF tube
- High Flow Double Cone Air Filter
- Aluminium Cowl for smooth airflow entry
- Prepreg Carbon Scoop
- Prepreg Carbon filter shroud
- CNC Machined MAF Boss
- Double layer main heat shield
- Double layer secondary shield
- Laser Cut Mounting Brackets
Dyno Graph (Click to enlarge)
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.
