More Cold Air = More
Horsepower
The basic purpose of the air intake system is to
bring cool air from outside the engine compartment
into the engine. The cooler air is denser than the
air found within the hot engine compartment. The
denser charge contains more oxygen than warmer air,
providing better combustion through a more effective
air/fuel mixture.
Another advantage of most
specialty-equipment cold air intakes is their
consistent diameters and the absence of sharp bends,
both of which help to eliminate turbulence in the
air stream.
Large and Growing Market
According to research done by the Specialty
Equipment Market Association (SEMA), a new air
intake system is among the first modifications a
consumer makes to his or her vehicle. Since changing
the air filter alone cannot eliminate air
restriction built into the vehicle at the factory,
replacing the factory air flow assembly includes
replacing the filter, air box and air path. SEMA
reports sales of air intakes are over 300,000 every
year.
While intake kits were initially
sold only for performance-type applications, they
are now also being marketed and used as a way to
boost fuel economy in SUVs, minivans, trucks and
more.
AMSOIL EaAU
AMSOIL Ea Air Induction Filters fit most of the
popular intake systems available. They provide
improved cold air intake and a level of engine
protection only an Ea Filter can provide. AMSOIL is
currently offering nine Ea Air Induction Filters
with varying lengths and widths. These filters have
flange IDs of 3", 3.5", 4", 4.125”, 4.5” and 6".
Since these filters offer a universal fit, AMSOIL
provides the dimension sheet below that customers
can use to determine the proper filter for their
applications.
Cleanable
AMSOIL Ea Air Induction Filters are cleanable and
long lasting. AMSOIL recommends cleaning the Ea Air
Induction Filter when designated by the restriction
gauge if the vehicle is so equipped, or according to
operating conditions. If it is used in extremely
dusty environments or in a performance vehicle, more
frequent cleanings may be required.
Unique Design
To increase filter surface area and the volume of
air entering the engine, the top of many popular Ea
Air Induction Filters (EaAU) is cut away. The media
is inserted in a conical form pointing toward the
direction of airflow.
Quality Construction
AMSOIL Ea Air Induction Filters are made from the
same high-quality nanofiber media found in other
AMSOIL Ea Air Filters. The nanofiber media is
pleated with epoxy-coated wire on the face and back
of the media for additional strength and stiffness.
High quality, pliable urethane connectors with
plastisol potting complete the product. Each Ea Air
Induction Filter comes with a clamp for convenient
installation.

Dimensional Measurement Features (37k PDF)
AMSOIL EaAU filters
are designed to replace air induction filters on a
dimensional basis only. EaAU filters do not provide
connections for engine sensors found on some
aftermarket induction system filters.
