Product Name: Pro Dry S Intake (51-Series) Manufacturer: aFe Fitment Notes: 2011-2016 GM Duramax
Advanced Flow Engineering offers you a better choice of oil-free filters: New Pro Dry S synthetic dry-media filters. Pro Dry S filters use a revolutionary two-ply synthetic material that is functionally superior to traditional paper media and single-ply synthetic, and easy to service. Pro Dry S dry-media filters increase airflow providing improved horsepower, torque, and fuel economy with 99.4%* filtration efficiency. Perhaps the greatest benefit of new Pro Dry S filters is the convenience of servicing these oil-free filters. To clean a Pro Dry S filter lightly tap it on the ground, vacuum it, or wash with soap and water. Solvents and oiling are not necessary. Pro Dry S dry-media filters by aFe are now available on all of our popular air intake systems for gas and diesel trucks, SUVs, and cars. Replacement Pro Dry S filters for all air intake systems are also available and sold individually.
The pro-dry S oil free filter is the perfect balance of performance and convenience. The easy to maintain synthetic media provides huge gains and offers 99.2% efficiency.
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.
