Hi, Just purchased an MR2 and I noticed a whistling sound coming from the engine bay. I Located it to the air box where it seems there is a hole at the top of it allowing unfiltlered air to be sucked in. Any idea what hose is meant to go into that hole? if any?
Also there seems to be a lot of empty 'air storage units' as i call them connected just after the air filter, black boxes with nothing in them, just wondering whether they actually serve a purpouse...
