I think he is saying he has the PCV SUPPLY tube at the airbox, but the PCV return is still at the plenum.

He has an 05 so his adjustments to the PCV return are limited (uses stupid locking clips on the return hose and the PCV is heated)
The PCV supply is the larger one, before the t/b, and feeds the PCV system
