Ea Air Induction Filters (EaAU)
AMSOIL now offers universal air induction filters (EaAU) designed
to replace stock oil wetted gauze or foam conical filters that
were supplied with custom induction systems. AMSOIL Ea Air Induction
Filters offer better efficiency, excellent airflow and are cleanable.

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.
Cleaning
Carefully remove the filter from the housing. Clean the housing with a
shop towel, being careful not to knock contaminants into the air inlet.
Filters can be cleaned by carefully vacuuming the filter media on the
dirty side, or by holding the filter with one hand and carefully blowing
the filter media at a 45-degree angle on the clean side using low-pressure
shop air (15-20 lbs. psi).
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 indution filters on a dimensional basis.
EaAU filters do not provide connections for engine sensors found on some aftermarket induction system filters.
* Filters have optional port for engine sensor. Ensure this port is not required prior to purchasing the EaAU filter.
