Built to perform. The HRB Billet GR Yaris intake was designed to replace the factory plastic unit, increasing plenum volume, adding critical runner length and deleting the factory EGR manifold allowing the intake to bolt directly to the head. Designed around the trusted Bosch drive by system, the intake was shaped using 3D scans of the engine and engine bay, allowing us to squeeze every millimetre out of the design, critical on such a small car.
