Eventuri Carbon Fiber Engine Cover for FL5 Civic Type R

TAG Motorsports is pleased to offer the Eventuri Carbon Fiber Intake System for the FL5 Honda Civic Type R.

Peak Performance Gain : 14 whp, 15ft-lb

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.

The Eventuri FL5 Type R intake system consists of a number of components engineered to perform a specific purpose and fabricated to the highest of standards.

Introducing our Carbon Turbo Tube for the Honda FL5, which is a direct replacement for the OEM metal turbo tube. Utilizing the same design brief as our FK8 tube, we developed the FL5 version with these 3 key objectives:

1.) VOLUME : Inlet Diameters – Eventuri 78mm at the intake end, increasing to 88mm. In comparison, the OEM tube starts at 76.5mm and then stays at this diameter before reducing to the turbo inlet. This equates to an increase in cross sectional area of over 32% at the largest point. Although the OEM FL5 tube doesn’t pose a restriction to the turbo at stock boost levels, we expect our larger tube to benefit at higher boost levels where the airflow demand is increased.

2.) FLOW QUALITY : Having just a large internal volume is no good unless the flow path also allows for smooth airflow to the turbo. By using high temperature Prepreg Carbon Fiber we have managed to achieve a smooth internal surface. In contrast, the stock inlet tube is made from cast aluminum which ends up with a rough internal surface. This coupled with the smooth curvature of the elbow results in a flow path which minimises turbulence.

3.) TEMPERATURE : The final criteria was to minimise the conduction of heat into the airflow. The stock inlet is directly connected to the turbo and so immediately conducts heat as the turbo spools. Our system uses a machined flange which connects to the turbo and then a silicon coupler with an integrated thermal spacer to keep the carbon elbow from having direct contact with the turbo. This barrier coupled with the low through-thickness thermal conductivity of carbon fiber results in less heat being transferred to the airflow.
