Mods to factory air box and air pipe change ?

I found this one but is for a previous Silverado model:

I did something similar with a AEM dryflow and airaid M.I.T. intake tube. And gained breathing for sure, how much hard to tell as I know the AFE GT momentum I have now gave a whole lot more.

 

But as a free or low cost mod its pretty worth it as long as you live in a climate where water/moisture will not be an issue. In reality probably is as good or better than a lot of the poorly designed aftermarket intakes.
