If you cut it it should work fine. Just cut it evenly and cleanly. Don't mess it up. All it is really is a pipe with a filter on the end. And which hose are you talking about? there should be a hose that has air directed from the fan going to the stock filter and a hose leaving from under the filter with a MAF sensor attached. The senor should have a wire coming from it then it should enter the throttle body.
