Is This Airbox Mod of Any Benefit?

I found this how-to, and I was wondering if anyone here has done it and if there would be any gain from it besides noise? thanks!

Modern stock air intake systems are usually very efficient if for nothing more than improved fuel economy.

i opened up my box to take a look and it didnt have that white attachment, so no dice. i would have given it a shot if it had been there.
