I was just looking at my stock air box and I noticed there is a plastic extension tube that attaches to the airbox, it pops right off. After taking it off it looks like it allows more air into the airbox but that comes with a prices, a louder intake sound. 
I just took my car for a quick run and it sounds a little louder at WOT and maybe a little more punch to it.
Anyone ever done this? Sorry I'm new, this may have been talked about before.
