Air intake
An air intake (or simply an “intake”) is a part which supplies intake air, a resource required by jet engines. To do so they must be in their “Open” state and inside an oxygenated atmosphere, such as that of Kerbin or Laythe.

[hide]Usage
Intake air collected varies proportionally with speed and inversely with altitude. Intakes cause the same amount of drag whether open or closed.[1]
Seaplanes and boats have also been made with unorthodox use specifically of the XM-G50 Radial Air Intake. With 1.0.5, improved hydrodynamics make this unnecessary for building boats or seaplanes. Intakes can also be used as a sort of nose cone to reduce drag on rockets.[1]

The values of masses in the table don't consist the mass of the intake air (5 kg/), as you can see in the SPH/VAB.
