Eventuri Carbon intake system for BMW M5 E39

The Eventuri sports intake system is made entirely from the highest quality carbon.
The system provides improved performance, faster throttle response, and a distinctive sound.

Filtration and Construction

Unlike many intake system manufacturers that use standard filters, through extensive research and development efforts and investments, we have developed a unique filter design that provides optimal performance parameters thanks to a patented reverse configuration. The filter material is made from a non-woven mesh tested according to ISO 5011 and meets the requirements set for factory-installed filters. The mesh consists of two layers and is completely dry, meaning there is no risk of damaging the mass airflow sensor due to oil contamination. The filters include two cones that direct airflow as described below: 

1. Inner Cone – facilitates the direction of incoming air through the filter and ensures a uniform velocity profile of airflow across the entire length of the filter material. The cone allows for efficient airflow through the filter without disturbances.
2. Outer Cone – machine-manufactured with a unique profile and optimal shape that facilitates airflow inward, towards the bottom of the cone, and smooth flow into the downstream intake pipes. The cone creates a controlled area of flow disturbances around the outlet tip, ensuring convergent airflow at high speed and a high-velocity airflow profile in the ducts leading to the engine.

Airflow

The airflow through the filter and the outlet from the intake system to the connecting pipe to the engine is smooth and occurs at high speed. In practice, this means that the engine has the ability to intake air very effectively, resulting in a quicker response to throttle opening, as well as an increase in engine power and torque. In the case of turbocharged engines, due to lower airflow resistance, it is possible to achieve peak boost earlier. Tests have shown that our intake systems significantly reduce the throttle cycle of the exhaust compared to factory-installed systems.

The following diagrams present CFD (Computational Fluid Dynamics) simulations of streamlines and velocity distribution for the system with the new and original filter.

Improvement of Parameters

Tests of Eventuri intake systems with original and new filters on the dynamometer have shown an increase in engine power and torque. This allowed us to verify our theoretical models and prove that the new, improved filters significantly affect airflow through the intake system. The increase in power compared to the original filters depends on the vehicle. Below are the results of measurements conducted so far. These graphs show a comparison of the Eventuri intake system with the original and new filter. Results for factory intake systems were not compared, for which the improvement in parameters will be even greater.
