Product Name: AFE Momentum HD Pro Dry S Cold Air Intake System Manufacturer: AFE Manufacturer Part #: 51-74002 Thoroughbred Diesel Part #: AFE51-74002 Fitment Notes: 2004.5-2005 GM Duramax 6.6L LLY
Bringing you the next generation of intakes, the Momentum HD sealed air intake system is designed using the most up-to-date engineering tools and techniques to provide you with the perfect blend of power and protection. This intake system is superior in every way. From the one-piece sealed housing with a built-in sight window to the massive 1,000 cfm air filter and premium hardware, we spared no expense to give you the best intake on the market.
Unique One-Piece Housing: The smooth one-piece sealed housing with auxiliary air scoop is used to eliminate the use of multiple-piece housings and ensure the coolest air intake charge available. A urethane plug is also included for extreme conditions when you want to block the auxiliary air scoop. A large, clear sight window is used for a hassle-free filter inspection.
Roto-mold Tube: This System uses a CAD designed, dyno-tuned, roto-mold intake tube to achieve maximum power gains while maintaining a perfect fit.
Huge Pro DRY S Performance Air Filter: This Momentum HD is designed around a massive Pro DRY S performance 360 degree radial flow air filter with 3-layers of progressive synthetic media providing 99.2% cumulative efficiency. The unique air filter to housing interface (PATENT PENDING) allows for maximum filter size which increases the available air volume while simplifying the installation process. The air filter is wrapped in reinforced metal providing maximum strength to prevent filter collapse.
Premium Hardware: Premium stainless steel T-bolt clamps and a reinforced silicone coupling at the turbo inlet is used for strength and durability while also providing the most secure installation available. Momentum HD intakes are designed with fewer parts for a quick and simple installation.
Proven Results: After a rigorous design and testing phase, the results are in. The Momentum HD intake system outflows the factory intake by 43% and resulted in 19 additional horsepower and 33 lbs. x ft. torque.
Power, Protection and Simplicity.
AFE Momentum Intake Features:
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.
