The difference between a sufficiently powerful truck and a real workhorse of a truck often comes down to how good that truck's air intake is. Banks Cold Air Intakes are designed to get a significantly higher volume of cold air into your engine's combustion chambers. This cold air carries with it a higher volume of oxygen, which creates an air-fuel mixture that burns more completely. This directly leads to more power and more torque. The first step in the Banks Cold Air Intake is the performance air filter. Compared to your old, stock air filter, these are huge. These filters have all the filtration capabilities of stock air filters, but they do not compromise air flow as many stock filters do. As such, more air passes through these filters thanks to its huge surface area and outlet. Then, the air flows through the streamlined ducting, designed to significantly curtail resistance air might face that would otherwise cause it to back up. Also, the cold air box is fully enclosed to keep out hot engine air so that only cold air passes through this intake. All told, a Banks Cold Air Intake can improve airflow into your engine by up to 40 to 50 percent.
