Well I plugged the hole in the intake that goes to the mysterious resonator in the airbox and I cannot tell even the slightest bit of a difference. I wasn't expecting power increases but I can't hear even the tiniest amount of a change in the sound. Apparently GM spent thousands of hours and probably millions of dollars designing something that is absolutely pointless. It really surprises me that they are headed for bankruptcy! Don't get me wrong I'm a huge fan of the General and even own stock right now but spending time, money and resources on items like this which are useless just boggles my mind.
