If it didn't start hissing until you put the filter in, you probably didn't seal the box. The top of the airbox fits OVER the bottom. (and the filter) creating a seal.
The filter<s> all have a bad habbit of wiggling into the way of the box so it doesn't get a good seal.
If that's not it, check for loose/ split vacuum hoses.
