These Weeks Brothers airboxs are designed to go onto a 38, 44 or similar carb bases made by NPP or Wax (and others) Comes with hardware. The design incorporates a fogging port on the top of the box that splits and provides oil to both cylinders simultaneously. Plenty of air in, and you get to retain your OEM flame arrester screens in the configuration you require. Avoids the rear cylinder getting less air due to OEM design and having to be jetted differently. Pulls air from over the motor to avoid water ingestion from in the hull when the hull is upside down.
