Location of intake hose, intake valves

The air intake hose is the large diameter black tube going from the large black box (where the air filter goes) on the driver side of the engine bay, to the aluminum (silver colored) piece behind the engine (the intake manifold).

The "intake valves" themselves are internal to the cylinder head and not visible from the outside. If you're actually asking about the throttle valve, that should be between the black intake hose and the silver intake manifold.

However, my guess is that these questions are leading to a bigger question. What are you trying to accomplish by finding these parts?
