Outflows stock by 73. Cold - air intake with large lifetime filter, enclosed housing and large tubing offers huge improvements over stock flow, increasing power and fuel economy. Banks Ram - Air Intake System replaces the factory's flat panel filter with a large conical filter that provides maximum high - flow filtration. The Ram - Air's opening dwarfs the stock's inlet, and without the 90 - degree detours that choke airflow and kill power.

The results are impressive Banks Ram - Air outflows the stock intake by 73, improving the Jeep's power and fuel economy. And Banks Ram - Air is designed to accommodate engine movement, which prevents component damage for reliable service life. US Patent 10,138,851 B2
