Example of a Roush cold air intake system installed on a sixth generation Ford Mustang Illustration of how the first generation Honda Ridgeline's cold air intake system gets fresh air forward of the radiator and into its airbox using an air channel created by the bulkhead cover and rubber seals under the engine's hood.

Typical airflow in a four-stroke engine: In stroke #1, the pistons suck in (aspirate) air to the combustion chamber through the opened inlet valve.. A naturally aspirated engine, also known as a normally aspirated engine, and abbreviated to N/A or NA, is an internal combustion engine in which air intake depends solely on atmospheric pressure and does not have forced induction through a ...
Aircraft using piston engines use intake systems similar to automobiles. With the development of jet engines and the subsequent ability of aircraft to travel at supersonic speeds, it was necessary to design inlets to provide the flow required by the engine over a wide operating envelope and to provide air with a high-pressure recovery and low distortion.
The air intake (inlet U.S. [6]) is an aerodynamic duct extending from an entry lip to the engine fan/compressor. For supersonic intakes with variable geometry it is called an intake system, referring to the need for shock-wave and internal duct flow management using variable position surfaces (ramps or cones) and bypass doors.

Short velocity stacks on a 302 cu.in. Ford FE engine in the tight confines of a Ford GT-40. A velocity stack, trumpet, or air horn [1] is a typically flared, parallel-sided tubular device fitted individually or in groupings to the entry of an engine's air intake system to smooth high speed airflow, and allow engine intake track tuning to incorporate pressure pulses created by its internal ...
A shaker scoop (sometimes called a shaker hood scoop or a shaker hood) is an automobile term for an air intake for combustion air that is mounted directly on top of the engine's air cleaner and protrudes through a hole in the hood. Since it is fastened directly to the engine, it moves with the engine's movement and vibration on its mountings ...
