AMSOIL INC. revolutionized the filtration industry
with its introduction of AMSOIL Ea Air and Ea Oil Filters. For
the first time exclusive nanofiber technology the same
technology used in the Abrams M1 tank and other heavy duty applications
was made available for automotive applications. Now, AMSOIL
has made this outstanding new technology available for motorcycles.
Because the nanofibers in AMSOIL Ea Motorcycle
Air Filter media are so small, there are more pores per square
inch, allowing for higher dirt-holding capacity and lower pressure
drop compared to traditional filter medias. Thinner media fibers
produce more uniform pore size distribution, improving the filters
overall ability to capture and retain particles.
Air Filtration Basics
An engine requires air for combustion, but the
air drawn in through the induction system is loaded with contaminants.
There are over 400 tons of suspended dirt and other contaminants
in a cubic mile of air over a typical city. The concentration
can be even higher in rural areas where there is frequent travel
on unpaved roads. The dirt and contaminants drawn into an engine
from the air are the leading causes of engine wear.
The function of the air filter is to trap and
hold these wear causing contaminants without restricting air flow.
As the filter traps more and more contaminants, air flow becomes
restricted, smothering the engine and diminishing performance.
The more wear causing contaminants a filtration media traps and
holds, while still allowing optimum air flow, the better the filtration
The nanofiber technology used in AMSOIL Ea Filters
surpasses all other technology in efficiency, capacity and service
life. With AMSOIL Ea Air Filters, dust and submicron particles
remain on the surface and are trapped in the nanofibers, preventing
particles from lodging in the filter media depth. This produces
higher efficiency and higher capacity, extending engine and filter
life and reducing engine wear.
Ea Motorcycle Air Filters
The filtration media in the Ea Motorcycle Air
Filter is pleated and has epoxy-coated wire on the face and back
of the media for additional strength and stiffness. High quality
plastisol potting compounds bond the pleat packs to the plastic
or aluminum side plates. The S&S (aftermarket engine and carburetor
manufacturer) style round filters are manufactured with high-quality
plastisol that bonds the media to the wire backing and sealing
The synthetic nanofiber media featured in AMSOIL
Ea Motorcycle Air Filters have sub-micron diameters and small
inter-fiber spaces, resulting in more contaminants being captured
on the surface of the media and lower restriction. Cellulose,
wetted gauze and foam filters have larger spaces between the media
that cause contaminants to load in the depth of the filter, resulting
in airflow path plugging, higher restriction and lower capacity.
Cleanable for Long Service Life
AMSOIL Ea Motorcycle Air Filters are cleanable,
providing unsurpassed protection and long service life. AMSOIL
Ea Motorcycle Air Filters should be cleaned every year or according
to operating conditions. Operation in extremely dusty or dirty
environments may require more frequent cleaning. Ea Motorcycle
Air Filters should be changed every four years.
AMSOIL Ea Motorcycle Air Filters are cleaned
in the same manner as AMSOIL Ea Air Filters for cars and light
trucks: with a vacuum or shop air. To clean with a vacuum, place
the filter on a flat surface and carefully vacuum the filter media
on the dirty side where the incoming airflow enters the filter.
To clean with shop air, hold the filter with one hand and carefully
blow the filter media at a 45-degree angle on the clean side of
the filter using low-pressure (15 to 20 psi) shop air. Using too
much air pressure will damage the filter media.
AMSOIL is producing an initial offering of eight
Ea Motorcycle Air Filters manufactured for the most popular Harley
Davidson models from the years 1988 to 2006, including motorcycles
equipped with S&S carburetors and air cleaner housings.
