So I've searched for a description of the sound, and I couldn't find anything. I believe that the slit vacuum hose, wrapped around the inside of the hole in the heat shield/intake holder is the most recent fix for it, though it doesn't completely eliminate the sound. I was just wondering if someone could describe the sound to me, because I've recently been hearing a new sound when it's cold outside. It's annoying the hell out of me, and I'm wondering if it's just the intake rubbing, etc., or if it is something I should really look into. Thanks.
