AFE OE Direct Fit Stock Replacement Air Filters

Description

aFe Direct Fit OE Replacement Air Filters. aFe's high performance, high flow OE air filters replaces the restrictive factory paper filter and lets your engine breathe better. Paper filters does a good job in keeping dirt out but can clogged easily so that it needs to be replaced frequently. Foam filters also clogs easily. The AFE Advanced flow engineering washable and reusable, cotton gauze filters like ours allows more airflow and is washable and reusable. Try a simple test. Put a sheet of tissue paper up to your mouth and draw air through it. Now put a sheet of cotton gauze and see the difference. What happened to the tissue paper when you got it wet? What happened to the gauze? Our filters are like that. Round, flat, oval, conical. aFe makes them all. With our filters, the engine can breathe a lot better. Have you ever tried running when you had a cold? It's hard when you can't breathe well, right? Your car's engine is the same way. When it is choked with a paper filter, it has to struggle to run at its best. When the filter is new and unclogged, it works fine but when dirty, the engine has to struggle. Stock OE paper filters get dirty quick. Our 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 lampshade. 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 our filters are, these strands attract dirt and dust particles. One or two layers would allow dirt and dust particles to pass through, therefore we stack multiple layers to catch progressively smaller and smaller particles, as small as 2 microns in size. The aluminum screen holds the layers in place. We design our filters differently than other cotton gauze filters. We design our filters to have the tallest pleats that the factory air box will let us. There two reasons for this, 1) Taller pleats means more filter material to hold the dirt and 2) Taller pleats means that the pleats can be spaced out more to let more air through. We also have different pleat geometry than others. Take a look at ours. 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 lets air flow through the tops and bottom of the pleats. These features allow our filters to breathe better.
We use 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 our filters stand up over the life of your vehicle, we 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. Another feature makes our filters unique is our progressive bump seal on our flat filters. This bump seal made of flexible polyurethane is compressed tightly in the factory air box for a sure leak proof seal even when the factory air box has uneven sealing surface. Some of our filters, especially for diesel applications, have expanded metal screens for additional rigidity. In a turbo diesel application, the turbo will create a vacuum as it spools up and draws air into the engine. If the air filter is clogged, it not unheard of for a paper filter to sucked into the turbo. This is not a very good for a diesel engine. aFe embeds the expanded metal screen into the polyurethane for a secure lasting fit. On our round or oval filters, we insure a tight seal against leakage by designing in small ridges that are compressed as the filter is placed on the stock inlet. Being constructed of 100% polyurethane, the flanges and the ridges guarantee excellent fit no matter how often you wash and reuse our filters.

• Pro-Guard 7 Air Filter Features: To address the need for extra protection from dust and dirt with reusable oil-impregnated cotton gauze filters, aFe developed a new filtration technology so revolutionary that we applied for and received a patent.  This new filtration technology is aptly called Pro-GUARD 7.  5 layers of progressively finer mesh medical grade cotton gauze with micro fibers that attract smaller and smaller particles as air passes through is combined with 2 layers of random-porosity non-woven synthetic polyester fabric.  This 7-layer combination of cotton gauze and non-woven polyester is sandwiched between 2 layers of epoxy coated aluminum wire mesh.  Because of compression ignition of diesel engines, tolerance is much tighter than in a gasoline spark ignition engine.  These tight tolerances require clean air and lots of it.  Diesel engine require 7 times more air than a gasoline engine of equivalent size. The patented Pro-GUARD 7 filter media delivers more cool clean air needed for extended engine life, better fuel economy and additional power.

AFE OE Direct Fit Stock Replacement Air Filters - How It Works

Multiple Layers of Gauze Our 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 our filters are, these strands attract dirt and dust particles. One or two layers would allow dirt and dust particles to pass through, therefore we stack multiple layers to catch progressively smaller and smaller particles, as small as 2 microns in size

Pro-Guard 7 Ply Media When you use your vehicle in a severe duty or work application, it is important to give the engine a high level of protection from dirt and dust. With 7 layers of media, Pro-GUARD 7 is able to offer the level of protection to the engine that is unsurpassed of any washable/reusable filters. Even fine dust is effectively filtered out and kept from entering the engine intake. When the vehicle needs to make it through the long haul, Pro-GUARD 7 will offer the protection you need. Take a simple "white glove or towel" test. Wipe the inside of your intake tract with white cloth and see if there is any dust.
