I probably wouldn't feel comfortable running that filter on the street , would for track only bike for sure . I do run a well oiled BMC race filter though , that seems to catch all sorts of crap okay . Got two so rotate and so always one ready to fit and reseal the box quickly . I really like that Montgomery carbon airbox , be great on race bike , maybe even selectively ridden project bike , but that uses no filter at all . Guess you got to weigh up the gains verses potential risk with any filter choice other than factory original .
