Default What part of the engine is this?

I am guessing this is the air intake but I have never seen any air intake of such monstrous proportions.

Yes, I think you are right. Looks like a naturally aspirated engine to me. But where is the throttle body,is it concealed inside those huge air intake(inlet manifold)?

That looks like aerodynamic fairing to me. That is just like the aerodynamic fairing in F1 cars.

Yeah, you can call it that way also. An aerodynamic faring which helps the engine to breath better.

This is the airbox assembly. It usually houses the air filter, intake manifold, throttle body/s and runners.
The car will have an engine cover, so this part does not need to aerodynamically efficient, but it takes takes the shape of the required intake manifold and other components.

@ Jalsa777 , What are runners?

@ecenandu, I looked up aerodynamic faring on google, as I don't know what it is. If it is just cosmetic modulations to improve air flow over an automobile, then how does it matter in this case as it will be covered by the body.

Runners are basically pipes which flow from the intake manifold (airbox) to the intake ports on the engine head. The length and diameter of the runners decide the velocity and pressure of the air flowing into the the engine and thus affect the power and torque characteristics of the engine.

A slightly technical discussion can be found here. Its a good read though.

You are right about aerodynamic fairing. But as I pointed out in the previous post, in this case it won't have any effect because the engine bay will be covered by the body

Yes, you are correct one cannot call it as a aerodynamic fairing. And the link posted by Jalsa777 is a good read.
