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.

“Each dawn is clear
Cold air bites the throat.
Thick frost on the pine bough
Leaps from the tree
snapped by the diesel”

And each part of the whole falls off
And cannot know it knew, except
Here and there, in cold pockets
Of remembrance, whispers out of time.”

With short shrill Shriek flits by on leathern Wing,
Or where the Beetle winds
His small but sullen Horn,”
