aFe

Round, Flat, Oval, Conical...aFe Makes Them All!

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 clogged easily so that they need to be replaced frequently. Foam filters also clog easily. A cotton gauze filter like aFe's allows more airflow and is washable and reusable.

With aFe filters, the engine can breathe a lot better. With a restrictive 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. A stock OE paper filter will quickly become clogged as it become dirty.

The engine breathes better even as the filter gets dirty with aFe filters. 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 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.

Different than other cotton gauze filters, aFe designs their filters to have the tallest pleats that the factory air box will allow. Taller pleats mean more filter material to hold the dirt and taller pleats mean that the pleats can be spaced out more to let more air through.

Their filters also have a different pleat geometry: 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 make aFe filters 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 their filters stand up over the life of your vehicle, aFe has 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 than the factory filters use. A 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.
