Description
This design is heavily inspired by danobrien's design which replaces the non-ABS washer bottle and uses it's bolt holes in the firewall. This is my own design as I required a smaller adapter to fit 57mm/2¼" piping to connect to the stock airbox. It's currently a work in progress but my prototype did fit perfectly (see image) but the larger sized adapters might need adjustments to clear the weld lines, so I've provided the FreeCAD project file. 57mm / 2¼" piping 63mm / 2½" piping 70mm / 2¾" piping 76mm / 3" piping
