Nothing in the entire intake system from air filter to the intake
manifold has a "foam filter in the middle."

The only thing I can think of that could match your description would
be part of the crankcase breather system.  That hose does commonly
fail with age, turning mushy-soft and either collapsing or breaking
apart.  If it starts leaking, it introduces a big vacuum leak.
