I noticed the other day that when I took the lid off my OEM Air Box it was really loud, and just at idle, not sure if it's suppose to be like that, it's faint when the top is on but super loud when it's off, any input would be great, I tried searching around and didn't find anything, except something about some lines being crossed but now I cannot seem to find that thread :s

franky

yes thats normal.

Thank you,I've never really noticed it before, and thought it was odd, considering guys say they like taking it off for some sound sometimes but, its really loud vacuum lol O.O
