My two cents.

Mine still has the stock type filter and the stock air box. Just want to be sure that something isn't wrong. Don't want passengers thinking that I'm having gas.

I guess a lot of owners have this, must not be too bad.

LOL. Did you put in a K&N filter into the stock box? You might hear it a little then, maybe. Otherwise I'd check the seal between the box and the TB (if you haven't already), the stock air box can be difficult to reseat properly.

I had a cracked vac tube that went into the MAP sensor that made a hiss. Check the tube that goes straight into the front of the TB.
