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.

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.
