A cold air intake is an aftermarket assembly of parts used to bring relatively cool air into a car's internal-combustion engine.
Most vehicles manufactured since the mid-1970s have thermostatic air intake systems that regulate the temperature of the air entering the engine's intake tract, providing warm air when the engine is cold and cold air when the engine is warm to maximize performance, efficiency, and fuel economy. Aftermarket cold air intake systems are marketed with claims of increased engine efficiency and performance. The putative principle behind a cold air intake is that cooler air has a higher density, thus containing more oxygen per volume unit than warmer air.

Famous quotes containing the words cold and/or air:
“For, brother, know that this is art, and you
With a cold incautious sorrow stricken dumb,
Have your own vanishing slit of light let through,
Passionate as winter, where only a few may come:
Not idiots in the street find out the lees
In the last drink of dying Socrates.”
—Allen Tate (1899–1979)
“As far as I can see, this autumn haze
That spreading in the evening air both ways
Makes the new moon look anything but new
And pours the elm-tree meadow full of blue,
Is all the smoke from one poor house alone....”
—Robert Frost (1874–1963)
