An automobile has many essential parts which are required for their proper functioning. A Cold Air Intake is one of these. This very important device is used for bringing down the temperature in a vehicle when it gets heated up when driven for long time. The vehicle is then cooled up by letting in low temperature air inside the car’s internal combustion engine. This helps in increasing power as well as of the fuel and engine, thus making the car more efficient as a whole.
A cold air intake helps in reducing the air resistance by smoothing the interior of the engine. It also provides a direct route to air while shortening the length of intake. With the use of a less restrictive air filter increases the airflow capacity.
A cold air intake has certain advantages, which include enhancing the efficiency of the engine, while providing efficiency of fuel as well, thus giving fuel economy. It draws greater volume of air. This is cooler, thus providing more oxygen for combustion. When cooler, oxygen rich air is provided to the engine, the combustion of fuel is more efficient. There is proper mixture of air with the fuel, since the right amount of air is mixed with fuel. This enhances fuel efficiency, and utilization of fuel increases. There is smoother combustion of fuel and air in the engine, and therefore, more power or torque is provided by the engine. Another feature of cold air intake is that it improves the throttle response and fuel efficiency of the car. As it enables intake of cooler air, which is denser, more amount of air is available to the engine. Thus, fuel economy is improved, saving costs along with.
Though it has disadvantages also. The intake system may allow water to enter along with air when the vehicle is driven on flooded or water filled roads. This may cause hydro lock also. This system can increase the amount of noise produced by the engine.
Cold air intake systems are available in the market in many materials. These include plastic, metal, rubber as well as other materials, like fiberglass, carbon fiber etc. One thing that should be taken care of in a cold air intake is that its opening for air should be large enough to allow entry of sufficient air in the engine. This facilitative proper functioning of the intake system, enabling better working of engine which in turn enhances fuel efficiency and the efficiency of the vehicle as well.
