hey guys. i was just wondering if anyone had experienced the same problem. i drive an '08 nhbp fa5 si. every time i go over about 73mph i get some weird rattling sound in my engine bay like something is loose or about to fall off. it only happens when i go up that high, like on the parkway or highway. nothing from high rev'ing or local driving. i recently just installed my first mod with the help of my mechanic friend, an injen short ram intake, but im pretty sure that its not the problem. we retightened all the bolts/screws and made sure its secure with no leaks. id be greatly appreciative for any help/info. thanks!
