The huge inlet, enclosed housing and much larger tubing reduce restrictions, dramatically improving airflow to the cylinders. Another key element is the tuned in.Helmholtz in. resonator which eliminates engine drone while maintaining a throaty sound. Banks Ram-Air Superiority. Cold-air intake with large filter, enclosed housing and large tubing offers huge improvements over stock flow, increasing power and fuel economy.
