I used 2.5 inch neoprene brake duct hose from Porterfield brake company. Rather than attaching a set of flanges to the air pass through I just jammed the hose directly into the airbox. With a little flexing of the hose it fits in perfectly.

Oh, yeah. I also routed the hoses around the outside of the crash bar. This required removing the air deflectors.
