Cold air intake systems come in many different colors and sizes, and are easy to install when compared with other performance-increasing modifications. All cold air intakes operate on the principle of increasing the amount of oxygen available for combustion with fuel. Because cooler air has a higher density (greater mass per unit volume), cold air intakes generally work by introducing cooler air from outside the hot engine bay.
