What The Heck Is This Gismo???

This is attached to the intake tube of my 2014 GT 5.0...what is it for??

That's your sound tube. Ford pipes some intake noise into the cabin through this to make the quiet muffler sound a little more aggressive. You can safely pull and cap it if you don't like it.

REALLY?? Sounds nuts but I guess it's better than LOUD PIPES outside!!
Don't think I paid any attention to interior sound since I immediately went to Magnaflows!!

Have any of you guys removed this "Sound Tube" and if so what was the result??
What plug did you use in the firewall??
Thanks!!

I removed mine. The result is a much cleaner looking engine bay. The interior is noticeably quieter. All I hear now is the exhaust. I have an Airaid CAI which can be installed with or without the sound tube, and includes the necessary plugs if you chose to remove it/ Here is a write up from another website on how to remove it:

I know the car in the write up is 2010 with a 4.6 but the tube is the same.
Here is a kit, with the necessary plugs. This makes it simple but I think you could get the plugs cheaper on your own:

Thanks for the reply Svtpilot!!
I plan to remove mine today and found an expandable rubber freeze plug that fits the intake tube hole perfectly and a Master cylinder gasket for the firewall!!
I'll let ya know how it works out!!

I took the gray foam out of mine today and it sounded terrible so I just removed the whole thing and it sounds much better to me with my Magnaflows!!
I found a good way to plug the intake tube for less than $5.00......an expandable freeze plug from Advance Auto Parts.....works GREAT and looks important!!
I used the Master Cylinder Gasket from Dorman (#42098) on the firewall......looks OEM!!
Now.......on to the next project!!

I need to remove mine from the CAI just to see how it will sound. Not a big fan of that "qwish" sound from the cone filter.

I took mine off and put it back on........other than the silly looks it is OK for WOT sound with the windows up!!
