Cars are able to breathe easier through an effective car air intake system while creating additional horsepower and extended gas mileage. Standard air intake systems installed in cars tend to be restrictive in the sense that engine power or efficiency is sacrificed in exchange for noise elimination. This is the reason why aftermarket cold air intake systems have become quite popular. Coming in all sorts of colors and sizes, the device can easily be installed to effectively lower the temperature by increasing the amount of oxygen that can be used for combustion with fuel.
The car air intakes being sold in the market have been designed to reduce airflow velocity through the increased diameter of the air intake. They have also been designed to provide an air intake route that is shorter and more direct primarily through the removal of muffling devices. Car air intake is not to be confused with the air filter system.
The device can be constructed from metal, rubber, plastic or composite materials such as fiberglass or carbon fiber. Car air intakes should be able to provide a measurable increase in horsepower and acceleration if it is to be considered as doing its job. Most have been engineered for specific vehicle designs. Prospective buyers should however check if a particular car air intake model is street legal in their state especially where certain emission standards are in place.
