Banks Ram-Air® Intake System 3.8L 6-CYL: 2007-11 WRANGLER Banks Ram-Air Intake System replaces the factory's flat panel filter with a large conical lifetime 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 huge inlet, enclosed housing and much larger tubing reduce restrictions, dramatically improving airflow to the cylinders. 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. Application: Ram-Air Intake System 3.8L 2007-11.
