This 02-05 Honda Civic Si AEM Dual Chamber Cold Air Intake System uses a patented dual chamber design (using two different diameters and lengths of piping), to create multiple frequency sound waves that help charge the cylinders with cooler air throughout the entire rpm range. Cooler air carries more oxygen, which translates into a more intense explosion in the combustion chamber to create more horsepower and torque.
