EVENTURI Intake for BMW with B58 engine
Fitment for all BMW G2x 3 and 4 series
with B58 engine (40I)
built after November 2018.
The G2x B58 OEM airbox system was updated in cars built after November 2018 where the airflow sensor was replaced with a temperature sensor in the inlet tube.
The BMW G2x B58 Eventuri intake has been developed to provide the turbo with a less restrictive flow path whilst maintaining low inlet temperatures.
Crafted from Prepreg Carbon Fiber, the airbox serves 2 objectives – to seal the filter against engine bay heat and to provide a dual cold air feed.
With a smooth inlet track to the MAF tube/Engine inlet and by ensuring Eventuri has an effective cold air supply to the filters, the resultant performance increases translate to an enhanced driving experience:
- Throttle response is sharper as air speeds in the inlet track are maintained by the Venturi effect
- Low/mid-range torque is increased which improves general drivebility. The car feels more aggressive and eager to drive, like an engine tuning performance.
- Top end power is increased as the engine is allowed to draw in cold air with less restriction.
Couple the dAHLer engine performance tuning increase with a more audible and sonorous induction sound and the overall driving experience is much more involving and more fun.

Why Eventuri Intake?
EVENTURI INTAKE SYSTEM BMW Gx B58 engine
The Eventuri for BMW and BMW M car is a new type of intake design, which has been granted a patent. Eventuri uses a cone filter – but here it is inverted and decoupled from the inlet tube. By removing the direct connection between the filter and the inlet tube, the filter is no longer dictating the shape of the airflow. This is now being done by the carbon housing, which is designed to smoothly guide the air into the inlet tube without a sudden change in geometry.
This means that Eventuri keeps laminar conditions throughout the intake, which is a lot more efficient. Furthermore, the funnel-shaped housing invokes the Venturi effect where the smooth reduction in cross-sectional area along the length of the housing causes the airflow to increase in velocity. Essentially the entire housing acts as a large velocity stack. On the road this translates to more power with a smoother delivery as well as sharper throttle response since the airflow is not inhibited by abrupt geometry changes.
RESULTING IMPROVEMENTS FOR BMW Gx with B58 engine
Dyno testing the Eventuri intakes back-to-back with the original filter vs the upgraded filter, Eventuri has found an additional power and torque increase for tuning BMW and BMW M cars, like an engine performance tuning module. This validates our theoretical modelling and proves that the upgraded filters really have a significant impact on the airflow through the intake. The power gains over and above the original filters vary between vehicles, but here are some of the results Eventuri has measured so far.
