Like your body, your car's engine needs rest because continuous combustion from everyday and long-distance driving might cause it to burn out. To keep that from happening, you must get your car a cold air intake system if it doesn't have one yet. This will keep the temperature of your engine down by allowing more oxygen into it, thereby maximizing combustion and making the burning of fuel become more efficient. It will in save you on gas, boost your horsepower, and stretch the life of your internal-combustion engine.
Thus, the cold air intake system can well take the place of your restrictive airbox and stock air paper filter, both of which squander horsepower. It has metal or plastic tubes that lead to a special air filter called short ram air intake. The increase in airflow is made possible by the big diameters of these tubes and their smooth interiors which reduce air resistance.
Air intakes come in many different styles and are constructed from different materials. Some are made of only one type of material (either one of plastic, metal, rubber or silicone), while others are made of composite materials (fiberglass, carbon filer or kevlar combined). The type of material used, however, does not affect the process because of the very brief contact of the material and air during tubing.
