That's the Plenum.

I think just about everyones builds up the oil residue like that over time.

It is oily ccv residue circulating through the intercooler and tubes.

Take the ccv fumes out of the system.

The oily residue comes from the CCV hose under the plastic connector in the air intake. The "CCV mod" will eliminate the oily residue in the intake and intercooler tubes. Sometimes folks will have intercooler tubes blow out of the blue connector boots due to the oil film. It can be a PITA trying to reconnect intercooler tubes on the side of the road.
