Cold air intakes are popular performance accessories for vehicles, added to create a more powerful and more efficient engine. Some new vehicles have a cold air intake as a standard feature, but performance enthusiasts generally have a low opinion of these intakes. Aftermarket systems are less restrictive and more stylish than the standard ones.
Cold air intakes bring cooler air into the engine from outside the system. Cold air has more oxygen than warm air, and this extra oxygen generates more horsepower, improving performance and acceleration.
Another purpose of a cold air intake is to increase gas mileage. It helps the engine run cooler, and a cooler engine operates more efficiently and burns less fuel.
Intakes can be purchased in numerous styles, shapes and colors, making them stylish as well as functional.
Performance enthusiasts often prefer the deep baritone sound of the engine sporting an aftermarket cold air intake.
Because one purpose of a cold air intake is improved efficiency, these parts usually are manufactured of lightweight aluminum or polyethylene.
