Banks Power 42145-D Ram Air Intake System with Dry Filter for your 03-07 Dodge 5.9L Cummins offers the reliability and durability of a factory intake yet delivers astonishing airflow. It flows up to 64% better than stock and outflows Volant and AIRAID, thanks in part to the Ram-Air's huge filter area (fewer filter cleanings!), giant outlet, and the complete air filter housing with large side & bottom inlets. Banks Ram-Air collects & directs more power-producing cool, dense air to the engine, lowering EGTs and smoke and improving fuel economy, too! The cleanable and reusable dry synthetic filter traps the most dirt and debris. And Ram-Air is the only aftermarket intake with 4-1/2" bellows to accommodate engine movement. This prevents component damage and promotes reliable service life.
