Eventuri Carbon intake system for Civic Type R FK8

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

Filtration and Construction

Unlike many intake system manufacturers that use standard filters, we have developed a unique filter design that ensures optimal performance parameters through a patented reverse configuration, thanks to extensive research and development efforts and investments. The filter media is made from a non-woven mesh tested according to ISO 5011 and meets the requirements 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 airflow velocity profile along the entire length of the filter media. The cone allows for efficient airflow through the filter without disturbances.
2. Outer Cone – machine-made with a unique profile and optimal shape that facilitates airflow inward, downward towards the base of the cone, and smooth flow into the further intake pipes. The cone creates a controlled area of flow disturbances around the outlet tip, ensuring convergent airflow at high speed and an airflow profile in the high-speed conduits 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 can very effectively draw in air, which translates to a faster throttle response as well as an increase in engine power and torque. For 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 show CFD (computational fluid dynamics) simulations of the flow lines and velocity distribution for the system with the new and original filter.

Improvement of Parameters

Tests of the Eventuri intake systems with original and new filters on the dynamometer have shown an increase in engine power and torque. This has allowed us to verify our theoretical models and prove that the new, improved filters significantly affect the airflow through the intake system. The power increase 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. The results for factory intake systems were not compared, for which the improvement in parameters will be even greater.
