The GR Corolla intake system follows our GR Yaris system, developed through extensive temperature, flow, and dynamometer data logging. Because it is a turbocharged engine, heat and volume were the primary considerations during development. This intake system was developed to deliver the highest possible flow while maintaining the lowest possible intake temperatures. Each component was designed to provide a smooth, free-flowing path for the turbo. By ensuring a sealed system, we improved the OEM airbox IATs while increasing internal volume to reduce pressure drop and therefore turbo pumping losses. This allows the turbo to operate more efficiently and therefore reach maximum boost sooner, resulting in a net performance gain.

The filter itself has an outside diameter of 210mm or 8.3″ with a filtration surface area of ​​over 130,000mm^2. The patented Venturi housing has been designed to provide the maximum internal volume possible for the GR Corolla and provides laminar flow to the turbo pipe.
