Replaced that split air intake hose today. Got a Beck-Arnley brand replacement from Rockauto.com for $42 - half as much as the Dorman brand replacement (the Dorman did come with new hose clamps.) The B-A replacement hosei is actually a bit longer than the old stock hose but that did not inhibit installation of the replacement part.

That's not OEM. Better start saving up for a head gasket.
