The Mercedes M139 intake for the A45 and CLA45 has been developed to allow the turbo a smoother route for airflow to be drawn from. By redesigning the system to allow for a much more direct path, the turbo is able to generate boost with less drag and therefore reach target boost pressure sooner in the RPM range. This intake system has been developed to offer the highest possible flow rate whilst maintaining the lowest intake temperatures possible to produce a net performance gain. The de-restricted flow path also allows for turbo spool to be heard more clearly adding to the dynamics of the overall driving experience.

The Eventuri Difference

The Mercedes M139 Eventuri system uses our Patented Carbon fiber 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.

Dyno Testing

Our M139 intake has been independently tested by a Mercedes specialist tuner in the UK – MSL Performance. Several runs were done with the OEM airbox to get a repeatable result and then again with the Eventuri intake. Tests were done on the same day back to back. Results show an increase in torque and power across the entire RPM range – not just at the peak RPM, which is why the car feels more responsive and is able to accelerate faster through the gears.
