From five feet away, air
filters look pretty much alike. Viewed up
close the aFe difference is striking. It is
hard to think of air filters as art objects,
but when people see the aFe air filter for
the first time, the reaction is usually the
same: "Wow, it's beautiful!" The
visible quality of our filters is a direct
result of our attention to detail. There are
no magic bullets here, just the result of
doing a lot of little things perfectly using
the most sophisticated tools available.

Multi-Layered Progressive
Media
|
|
A closer look at our filter media and the
construction of our filter shows the
attention to detail that produces the best
air filter in the industry. This is
the aFe difference that results in increased
airflow, more horsepower, increased torque,
improved engine protection and longer filter
life. |

The
special oil-treated surgical gauze filters
out contaminating particles with less
physical obstruction than typical paper
elements. The oil is absorbed and wicked
through micro fibers of the surgical gauze.
Suspended particles are filtered out of the
air stream through static charge attraction
with the gauze/oil media.

Pleated Filter Media
Not all
pleated material are the same.
Competitive products, while attempting to
increase surface area, over pack the filter
with excess pleats, thus resulting in the
unfortunate side effect of choking airflow.
With others, the peaks and valleys are pinched
tightly into sharp points that also restrict
airflow. Tight pointed pleats constrict
the micro fibers at the face of the filters
diverting airflow at point of impact.
See the
rounded tips like a dolphin's nose. 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. .

The multiple layers of progressively tighter
mesh cotton gauze is sandwiched between two
layers of epoxy coated aluminum screen.
The aluminum wire mesh serves two purposes:
first, it removes and prevents large solid
particles from entering or damaging filtration
media; and second, it provides a lifetime
structural skeleton for the filter.

The unique pleats are
made utilizing equipment specially
designed for aFe to insure that the
pleats are consistent from one roll to
the next. No matter how tall the
pleats are, the curvature and spacing
of the pleats are constantly monitored
and maintained.

Seal Design
|
|
Poorly designed seals either permit
air leakage or distort the filter
housing. Many other filters use plastisol
or air/foam seals. Over time, heat and
chemical attack cause this material to lose
its elastic characteristics, which result in
seal failure. On the other
hand, foam type seals simply cannot
pass the test of time. Use of a
foaming agent reduces the amount of
polyurethane used in the part.
Minimal heat exposure tends to turn
this material into powder. The
aFe air filter features a superior seal
design with a 100% polyurethane material
construction.
Plastic/fiberglass air boxes to the
naked eye may seem even and smooth.
However, there are often unevenness that can
allow air to flow around the filter rather
than through the filter.
To insure that all the air flows through the
filter media, aFe incorporates a unique
progressive bump seal on our flat, round and cone
filters. As the filter is
compressed, theses bump seal made of
soft pliable polyurethane is squeeze
to fill uneven surfaces for an
airtight seal.

Filter
Construction
|
The
pleated air filter media is enclosed in 100%
engineering grade polyurethane construction
that is soft and pliable to seal properly to
the factory air box but strong and durable
to withstand high engine temperatures and
multiple use cycles.
To
insure that the pleats are evenly spaced and
retain their unique pleat geometry, the
pleats are held in place during the
manufacturing with special spacers.
The aFe air filter uses deeper pleats
than the competition. Using deeper pleats
means more pleated media, resulting in more
surface area for air to flow through while
reducing its restriction. The aFe air filter
is able to achieve this without choking
airflow using a precision crafted pleat
pitch, allowing smoother airflow into the
engine.
The aFe air filter is simply more
efficient than competitive products.
Multiple discrete layers facilitate
depth filtration, which contributes
to efficiency and promotes longevity
over paper filters, which depend on
quick clogging surface filtration.
In addition, oil in the media
enables the cotton gauze to filter
out particles at a higher degree of
efficiency without restricting
airflow.
