The aFe Stage 2 sealed cold air intake produces up to 28HP and up to 54 lbs. x ft. torque while out flowing the factory intake by up to 41%. Fully sealed in a durable commercial grade designed rotomolded air box, this air intake system features a 5-1/2" PRO DRY S washable/reusable, high filtration conical air filter that provides maximum filtration (99.2% efficient) and convenience (requires no oils to clean). This intake system features a heat-insulating molded plastic intake tube and a unique turbo adaptor that funnels air into the turbo for improved volumetric efficiency and maximum performance while lowering Intake Air Temps (I.A.T). The "oil-free" PRO DRY S performance air filter is constructed with 100% polyurethane for long life and multiple cleaning cycles. Utilizing factory mounting points, this system is easy to assemble and easy to install. Fully Sealed Design aFe engineers have designed a very sophisticated 2-piece sealed intake housing that keeps out warm underhood air and brings in cooler, outside air for a denser intake charge. 5-1/2" 360 Degree Air Filter A cone 360 degree round air filter is used for maximum filtration (99.2% efficient) and convenience (requires no oils to clean). The patented PRO DRY S performance air filter features 3-layers of progressively finer mesh synthetic "oil-free" media and is constructed with 100% polyurethane for long life and multiple cleaning cycles. Hassle-Free Installation ° aFe has developed this intake to provide a hassle-free installation that utilizes all factory mounting locations. This intake is 50-state legal (CARB E.O Number D-550-4).

  • Do I Want An Oiled Or Dry Cold Air Intake System?

    Eric Schumann | 5/16/2019

    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.
