Eventuri carbon airbox zwart LHD/RHD (Honda Civic 22+ 2.0 Type R turbo FL5)

The Honda FL5 intake is the culmination of iterating our FK8 system to provide an optimised solution, taking advantage of the increased space in the FL5 engine bay. By maintaining a sealed airbox we have minimised heat soak to ensure a constant supply of cold air to the turbo. Since the intake sits directly behind the radiator it is crucial that the filter is not exposed which would result in heated air being drawn into the turbo.

We have also replaced the OEM flexible intake hose, which creates turbulence and therefore increases drag. With the FL5 Intake, we’ve engineered a seamless path from the filter to the inlet tube, eliminating drag and smoothing the airflow. Engine movement is now catered for by the inlet tube itself, which can move within the airbox whilst maintaining a seal against heat.

Our carbon airbox has been designed to maximise the use of the available volume and minimised heat ingress. The resulting performance gains and aesthetics are industry leading for the FL5 Type R.

With an enlarged airbox and a direct airlfow path to the turbo inlet tube, our intake allows the turbo to reach peak boost levels quicker through a lower waste gate duty cycle. Our intake has been independently tested by Honda tuning specialists. The results below show the comparison between the stock airbox and the Eventuri intake system on a standard car with standard map and exhaust. Dyno runs were done back to back on the same day and with the hood closed.
