The Honda FK8 Type R intake is the result of extensive design iteration through dyno testing and flow analysis. It was developed to achieve two objectives – 1) Maintain low inlet temperatures. 2) De-restrict the turbo inlet path. The first objective was met by enclosing the filter inside a carbon airbox and using the stock seal against the hood to block out the heat soak from the engine. Since the intake sits directly behind the radiator it is crucial that the filter is not exposed which would result in a loss of power through high IAT. The second objective was met by removing the flexible tubing and optimising the inlet path with a Venturi stack connected directly to the filter. Furthermore, we added a second inlet to the airbox with a scoop pulling in air from the inner wing area. This almost doubles the total cross sectional area through which the turbo can draw from as compared with the single entry on the stock system. Our carbon airbox enclosure has been designed to maximise the use of the available volume and block all sources of heat. The resulting performance gains and aesthetics are industry leading for the FK8 Type R.

Each intake system consists of:

• Prepreg Carbon Fibre Airbox Enclosure
• Custom High Flow Air Filter ISO Tested
• Carbon Venturi stack with integrated MAF tube
• Secondary Inlet Scoop
• Full Silicon Joiner with Breather Inlets
• Laser Cut Bracket Work

Made from 100% prepreg carbon fibre of the highest quality, the workmanship on the housing is second to none. This encapsulates the filter and is mated to an anodised aluminum inlet cowl to ensure a smooth inlet flow path. The filter itself is a deep pleated, dry filter which has been custom made to our specification. The Venturi carbon housing smoothly shapes the airflow down to the MAF tube and ensures laminar conditions to reduce the drag on the turbo and also avoids MAF sensor errors. With the turbo able to draw air with less restriction, the engine is able to make more power.

The filter housing comprises of the high flow filter, aluminium cowl, V-Band clamp, laser cut bracket and the Patented carbon pod itself. The carbon pod shrouds the reverse mounted filter and smoothly shapes the airflow down to the intake tube. This geometry invokes the Venturi effect where the airflow accelerates whilst maintaining laminar conditions. It can be thought of as a large velocity stack - below is a diagram to show the comparison between our patented design and a regular intake system. Our bespoke filters aid the airflow moving through the housings and allow for an even velocity profile as the airflow exits the housings.

Shown here in red Carbon/Kevlar hybrid, the cold air duct has been designed to capture ambient air and funnel it to the filter housing. This is a key component in our system which ensures a direct and continuous feed of cold air to the filter no matter how hot the engine bay gets. The stock airbox and any other intake system without a cold air feed will suffer from heat soak and power loss as the engine bay rises in temperature. A neoprene gasket around the top lip of the duct seals it to the scuttle panel. Furthermore, there is a water drain incorporated at the base of the duct - a pvc tube is connected to this to direct water back out to the road.

For ease of installation we provide an OEM panel which has been precision cut to ensure a perfect fit for the cold air duct.

Our new carbon intake tube replaces the stock rubber tube and in doing so smoothens the path from the filter housing to the turbo inlet. The carbon tube incorporates a CNC machined MAF sensor mount so there are no further interfaces after the airflow leaves the filter housing. The tube provides a more gradual change in direction from the filter to the metal turbo inlet tube as compared to the stock rubber tube - this increases the flow efficiency further. Here is a comparison between the stock and carbon tubes.

The final component in our V2 FK2 system is the silicon hose which connects the carbon tube to the metal inlet tube. This part features an internal step which mates to the stock metal inlet tube and therefore eliminates the exposed wall thickness of the metal tube. Many aftermarket silicon hoses simply go over this metal tube and leave the end exposed to the oncoming airflow which results in turbulence. The photo below shows the internal step.
