I know only about the E36. I think that it is a 3 1/2 " hose,
although I have not actually measured it. It is slightly larger than
the intake whole on the airbox. I can't help you with an E30, but I
am sure that the same principal holds. A heat shield is for keeping
engine bay heat away from the open cone filter. I don't use an open
cone , nor do I think that a heat sheild is adequate. It will keep
out the heat, but it will not provide for forced, outside cold air.
With a cone filter and heat shield set up, the air comes from behind
the headlamp and trickles in from the radiator. With a sealed hose
coming from the grill, you get not only cold, outside air, but it is
entering the car with a certain amount of force, depending on the
speed at which the car is traveling. This is "ram air."
