Product Name: Ram Air Intake System
Manufacturer: Banks Power Fitment Notes: 2003-2007 Dodge Cummins 5.9L
The Banks Ram-Air Intake System delivers exceptional airflow and air density. Its large cotton gauze air filter requires fewer cleanings than competitive filters (stock's small paper filter is not reusable). With its giant 7-1/8" outlet, streamlined components and enclosed cold-air box that keeps hot engine air out of the intake, the Ram-Air flows up to 57% better than stock and up to 23% better than competitors. In addition to greater power, you'll enjoy improved fuel economy, lower exhaust gas temps and reduced black smoke. (An indicator of unburned fuel, black smoke is power you can see but not use!)
And Banks' unique 4-1/2" bellows accommodates engine movement, which prevents component damage and prolongs service life. Designed to not cause fault or error codes; lifetime warranty on filter element.
Available in Oiled Filter or Dry Filter options
The stock air intake system is highly restrictive. The cramped outlet has tight bends, the filter design is inefficient with minimal filtering area, and the air that it does draw in is warmer and less dense. The Banks Ram-Air Intake System is "clean-sheet" engineered to minimize restriction, maximize flow and filter area, and draw cooler, denser air from outside the engine compartment.
When you think about cold air intakes, there are two main components to consider. First is air filtration. When comparing oiled filters to dry filters the oiled will always filter out more particulate than the dry filter will. The added oil allows the cotton fibers in the filter element to trap more particulate matter as the air passes through it. The downfall is that in dusty environments the oil filters tend to get dirty quicker than the dry filter will.
The second component to consider on a cold air intake is performance, or how much air flow it allows. From the tests that we have seen, there is no difference in air flow between an oiled filter or a dry filter, if they are both clean. However, as we stated before the oiled filter will catch more particulate and become dirty quicker than the dry filter will. As a filter becomes dirtier, its performance decreases due to excess particulate matter restricting the air flow. Therefore, a dry filter will provide more performance over a longer period of time than an oiled filter will.
For daily driven trucks we recommend oiled filters, unless the truck is driven in an extremely dusty environment. We feel that the extra filtration power added by the oil is worth sacrificing the 1 or 2 extra horsepower you might get from using a dry filter.
