VCTS controls flaps which most people delete in the intake manifold, it consists long bar that goes through 3 of the runners (terminates before the last runner) and has 4 flaps (1 for each cylinder) that open and shut to allow more air flow when VVT comes on.

If you delete this for the added air flow (and to balance airflow as best as possible) it can make cold starts a little sputtery I am told. The flaps and bar normally get deleted for a PNP manifold.
