Production cars have specific-length air intakes to cause the air to vibrate and buffet at a specific frequency to assist airflow into the combustion chamber. Aftermarket companies for cars have introduced larger throttle bodies and air filters to decrease restriction of flow at the cost of changing

Aircraft with a maximum speed greater than about Mach 2 use intakes with variable geometry to achieve good pressure recovery from take-off to maximum speed.
