This plate is perfect for the stock hayabusa! Fits in the bottom of the air box where the Diaphragm Cont. Valve (#10 in diagram) is located in stock form. This Plate requires the small air box mod. The nozzle is mounted at a tested angle, so that the fan spray is directed towards the velocity stacks. Plates can be custom ordered with different oriented holes and even multiple nozzles. Please email for costs.
This should be secured with four screws (supplied) and RTV silicone to make an air tight seal.
