is there any type of ducting system for an e 36 on the market without having to take out the driver side head light?

If you still have the factory airbox, the original inlet snorkle runs out next to the grill between the radiator and headlamp assembly....you probably wanted to here something else but there isn't much of any room in there for any other kind of plumbing
and you'd need to pitch the entire lamp unit as it's one piece for a "ramair effect" without the airbox you might be able to plumb something 'cold' but "ram" ? ? ?
