These are pics of the mods done to my ski. The front air intakes are from Home Depot (shop vac hose, coupling, and 3” to 2” fernco reducer bushing from the plumbing isle) about $35 total. The hood has had the blockoffs cut in the gills then 3 1” holes in the liner each side. Maybe others on the forum will find these useful.
