Ok i'm probably an idiot for this but i just installed my new intake and it has 2 holes rather than 1 for the little tube... i just plugged the second with electrical tape for the time being but what is it for did i f-up my install somewhere? the old one appeared to only have 1 hole out.. so maybe its not me?

anyone have a better plugging idea or better yet a better place to use hose #2?
