Are you talking about the filter housings "cold air intakes" or the aluminum plenums on the heads? If it's filter housings, no I wouldn't trust something as critical as air filtration to some no name MiC crap. That's how turbo compressor wheels get sand blasted and piston rings chewed up.
Find one. Ask a friend. Ask a stranger. Someone has to have one collecting dust(litteraly) some place. Look high, look low, look sideways and look some more until you can get one.
