 The AFE Magnum Force Stage 2 cold air intake system for the 04.5-05 Chevy/GMC Duramax 6.6L diesel engine (LLY). (Part #54-10612)
The AFE Magnum Force Stage 2 cold air intake system replaces the factory air box and the OEM air filter with a housing and conical filter, replaces the restrictive factory intake tube, and the whole system can be installed in less than 90 minutes. This system improves your airflow up to 75%, improves fuel efficiency, improves throttle response, improves acceleration, increases your torque, and, depending on application, can give you up to a 25 horsepower gain. AFE's high performance, high flow OE air filter replaces the restrictive factory paper filters  and lets your engine breathe better. Paper filters do a good job in keeping dirt out but can clog easily so that they need to be replaced frequently. Foam filters also clog easily. A washable/reusable, cotton gauze filter like AFE's allows more airflow and is washable and reusable. The filters are built to let the engine breathe better even as the filter gets dirty. The multiple layers of cotton gauze are sandwiched between two layers of epoxy coated aluminum screen and pleated like a lamp shade. Have you ever looked at cotton gauze under a microscope? It has tiny micro fibers branching out from the strands. When the gauze is oiled like these filters are, these strands attract dirt and dust particles. One or two layers would allow dirt and dust particles to pass through, therefore they stack multiple layers with progressively tighter mesh to catch progressively smaller and smaller particles, as small as 2 microns in size. The aluminum screen holds the layers in place and protects the cotton gauze. AFE designs their filters differently than other cotton gauze filters. They design their filters to have  the tallest pleats that the factory air box will allow. There two reasons for this: 1) Taller pleats mean more filter material to hold the dirt and 2) Taller pleats mean that the pleats can be spaced out more to let more air through. They also have a different pleat geometry than others. See the rounded tips like a dolphin's nose? Others are more triangular and pointed. This rounded design allows the air to flow more efficiently around the tops of the pleats. Not only that, because it is rounded, the pleats aren't tightly pinched and let air flow through the tops and bottom of the pleats. These features allow the filters to breathe better. AFE uses 100% engineering grade polyurethane which is more flexible and will seal better in today's plastic and fiberglass factory air boxes. To make sure that the filter stands up over the life of your vehicle, they have urethane on all four sides of the filter, not just on the open ends. The polyurethane stands up to high engine temperatures and engine chemicals better that the plastomers that the factory filters use. Advanced Flow Engineering, Inc.

AFE 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. Traditional paper filters restrict airflow through a vehicle’s intake system, limiting the engine’s power potential. AFE's Pro Dry S dry-media filters increase airflow providing improved throttle response, horsepower, torque, and fuel economy. And at 99.4%* filtration levels, Pro Dry S filters accomplish all this without sacrificing engine protection. Perhaps the greatest benefit of new Pro Dry S filters is the convenience of servicing these oil-free filters. Most traditional paper filter manufacturers suggest that filters be changed at least every 12,000 miles. Pro Dry S filters have service intervals of up to 50,000 miles in standard driving conditions. Just imagine the convenience of servicing your filter one-fourth as often. And because the filter is oil free, service is easier and less time-consuming. To clean a dirty Pro Dry S filter lightly tap it on the ground or vacuum with a standard house or shop vacuum. A vacuumed Pro Dry S filter will return to 95% of its original performance and airflow characteristics. For a full cleaning the filter may be washed with soap and water to return it to near-new condition and 100% airflow capacity. Costly solvents and cleaning kits are not required to clean the new Pro Dry S filters. Choose your filter below:
