1988 Pontiac Station Wagon air intake

so i've liked this car for a while you know had fun times with it as a kid but never really looked under the hood so when i did i see this hose conection by the radiator that comes in right behind the grill something for the air to come into to get to the engine witch runs a little on the hot side it is gone this car
has a chevy big block 350 in it and needs all the air it can get so the question is what is this hose connection for and what do i need to hook it up and get more air to my engine also what is tis piece called
