anyone knows how this engine part is called?

I was looking trough some of my best motoring videos and suddenly while watching VTEC Magic they show the engine of the Prime Garage Integra Type R, and it didn't had a Intake Manifold & Air Intake it has 4 pipes that suck in the air (probably the same job as the air filter) directly connected to the Throttle Bodies. Now, my question was, how are these pipes called that are connected to the throttle body?

I took a screenshot of that part:
