The airbox will mimic this design I have for the TRX450R. Nice thing about this box is you can run it as an "airbox eliminator" or as a complete airbox, I think an airbox that can be configured for different riding conditions is key. To start they will be vented as shown. I'm working with another company in the snowmobile world that makes hydrophobic mesh, so the vents will be covered with this mesh. Looks like outerwears material except it doesn't let water, mud or snow in.
