Type R FK8 Update
Final update before the official release:
We have now extensively tested the system on the dyno and in doing so have updated the design for optimal performance gains.
The main thing to take notice of is that the location of the intake in the FK8 is prone to heat soak unless the filter is fully sealed. It sits directly in front of the radiator and fan which, when activated blows hot air into this area. So any intake which has an open cone filter will have high inlet air temperature values and this will cause a loss in power.
For a fully sealed system – such as the stock airbox, the issue is the opening through which the intake can draw air from.
When the hood is closed, the stock system breathes through 2 places:
1) The opening above the front bumper through a duct
2) The opening through the gap between the hood and the rubber seal
The total cross-sectional areas of these openings are approximately 33cm2 (see photo explaining the FK8 openings). Dyno testing showed that the airflow requirement from the engine was enough to render this total opening a restriction.
During dyno tests we made an opening in the prototype airbox to increase the size of the area through which the filter could draw air from. On the initial dyno run, this extra opening gave an increase in power but after the second run - this extra power quickly reduced as the intake pulled in hot air from the engine bay.
This left us with a challenge - How do we increase the inlet opening without drawing hot air from the engine bay?
Our solution
After extensive development we have designed a scoop which draws air from within the wing area – away from the engine bay heat and importantly – the opening is not in direct path of the radiator fan. This scoop sits underneath the airbox and seals to it with a rubber extrusion. The extra opening in the airbox has an area of approximately 28cm2 which means that the total area for the filter to draw from is now approximately 61cm2 which is an 85% increase compared with stock.
To conclude, the larger inlet area removes the restriction of the stock airbox. This factor coupled with our venturi tube design which ensures smooth airflow from the filter to the turbo tubes as well as our system being a sealed unit to keep inlet temperatures down result in genuine performance gains which are consistent.
Summary of Key Design Features
- Sealed Airbox to keep IAT low
- Venturi intake tube to keep flow laminar to the turbo
- Secondary inlet scoop to increase inlet area by 85%
- True Plug and Play – no remap needed and no engine codes
- Carbon Fibre construction to minimise heat soak through the airbox
- Stock mounting method for ease of installation
The new scoop is under tooling now and we expect to have the first full systems by the middle of March.

Having said that for sure the FK8 is a better car.
