The RSKI air box is a replacement for 1996–2020 Yamaha Superjets running stock dual 38mm carbs. Carefully designed for perfect clearance around the ADA Girdled Cylinder Head, it installs with zero modifications and works seamlessly with the OEM intake elbow.
 
This is the plastic upper box only. 
OEM base plate, screens, eblow and hardware are still required for a complete, factory plus style setup.
