aFe's innovative filter design is the next
evolution of the lifetime, user-serviceable filter. Unlike the
traditional oiled fabric filter which uses layers of cotton gauze,
aFe filters are made from 6 staggered layers of purpose woven
cotton fabric of decreasing weave size. This maximizes airflow
while ensuring that contaminates are kept out of your BMW's
Most applications are available in both Dry-type and
Oiled-type filter media. VAC stocks the type we feel works best for
each particular application so you don't have to worry about making
the right choice. if you want a specific type, we can have it to
you in quickly from our warehouse as well.
aFe designs their
filters differently than other cotton gauze filters. They design
their filters to have the tallest pleats that the factory air box
There two reasons for this:
aFe also uses a
different pleat geometry than others. Rounded tips like a dolphin's
nose replace the more triangular and pointed pleats found in other
brands. 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 increasing surface area and
ultimate flow potential.
100% engineering grade polyurethane is used which is more
flexible and will seal better in today's plastic and fiberglass
factory air boxes. To make sure that aFe's filters stand up over
the life of your vehicle, urethane is used 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 that makes aFe filters unique is their
progressive bump seal on their 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.
