Air box :

Also referred to as the air box, the air intake on Formula 1 car is positioned behind and above the driver’s head to capture high-pressure, relatively undisturbed air to cool and asperate the engine.

Inside the air intake is an expansion chamber (diffuser) that slows the air down and increases its pressure, ready for its passage into the engine inlet manifold.

The air duct is constructed around the cars roll bar.
