The GR Yaris Intake has been developed through extensive data logging of temperatures, flow rates and dyno testing. Being a turbocharged engine, heat and volume were the main considerations during development. This intake system was designed to provide the highest possible flow rate while maintaining the lowest intake temperatures. Each component has been designed to provide a smooth and clear flow path for the turbo. Using a sealed system, we have improved the IAT's of the OEM airbox whilst increasing the internal volume to reduce pressure drop and therefore reduce the pumping losses of the turbo. This allows the turbo to work more efficiently and reach peak boost pressure earlier, resulting in a net power gain.

The filter itself has an outer diameter of 210mm or 8.3" with a filter area of over 130,000mm^2. The patented Venturi housing has been developed to provide the maximum possible internal volume for the GR Yaris and ensures laminar flow to the turbocharger.

The Eventuri difference
The GR Yaris Eventuri system uses our patented carbon fibre housing which provides an aerodynamically efficient airflow path from the filter to the turbo. It's not another cone filter with a heat shield, but a unique design that creates the Venturi effect and maintains laminar flow conditions to reduce drag on the turbo.

Dyno testing
Our GR Yaris intake system has been tested by various renowned tuners worldwide, all of whom have reported similar results. The first dyno chart comes from RaceCal in the UK. Several runs were performed with the OEM airbox to get a repeatable result, and then again with the Eventuri intake. The tests were carried out on the same day with the bonnet closed. The results show an increase in torque and power across the rev range - not just at peak revs, which is why the car feels more responsive and can accelerate faster through the gears. The ambient temperatures during this session were 11.9 degrees Celsius for the OEM airbox and 15.6 degrees Celsius for the Eventuri - the temperature increase is due to the dyno cell heating up after the runs with the stock airbox.

The second set of results comes from Master Tuning Asia in Hong Kong, who tested the intake against the stock airbox on the same day and this time in warmer conditions of around 32 degrees centigrade. The systems were tested three times and all three graphs show gains across the rev range, with the third run showing the highest gain as the stock airbox struggled with the IAT.
