AMSOIL has brought Nanofiber technology to the motorcycle market. AMSOIL Ea Motorcycle Air Filters hold 15 times more dust than a wet gauze type filter.
Their nanofiber media removes 5 times more dust than traditional cellulose filters and 50 times more dust than wet gauze.

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 filter’s 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 media.
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
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
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.
