i just installed me some of the worlds finest cbr itb's. i live in a rural city in utah and im much afraid of sucking up a few leaves, dirt and an occasional squirrel. does anyone have any ideas on a filter for these? could the stock cbr airbox fit? right now i have a mesh screen over it to prevent loose vacuum lines and my alternator from being sucked into my combustion chamber.

 

We've been running unfiltered on the street for 5 months and haven't had an issue. For peace of mind it is possible to modify a stock CBR airbox to work with a large filter, plus K+N makes filters that will work with ITB's.
