Nanofiber Basics
Because the nanofibers in AMSOIL Ea Motorcycle Oil 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.
Oil Filtration Basics
Clean oil is vital to engine performance and durability.
Oil must lubricate, cool and clean the engine as it circulates.
In order to remain effective, it must be filtered as it cycles. The filter is connected to the engine sump, which
contains the oil pump. Full-flow filters pass all the oil
output from the pump through the filter.
The function of the oil filter is to remove the contaminants
introduced into the lubricating oil and prevent
them from reaching sensitive engine parts without
restricting normal oil flow to the various points requiring
lubrication. Internal sources of contamination include
wear products from the rubbing surfaces of the engine,
blow-by gases leaking past the rings of the pistons
and degradation of the oil itself. A filter must perform
well in the areas of efficiency, capacity, flow and life.
Ea Motorcycle Oil Filters
Ea Motorcycle Oil Filters feature a specially constructed
silicone anti-drainback valve and a nitrile sealing gasket
to go along with the full-synthetic Ea nanofiber media. The
anti-drainback valve provides excellent protection during
startup and remains flexible in all temperatures, and the
nitrile sealing gasket resists chemical breakdown, providing
excellent durability and ensuring long filter life. AMSOIL Ea Motorcycle Oil Filters are fluted for easy
removal from the motorcycle and are available in a
chrome-plated alternative to the normal black filters.
Superior Filtration
The unique construction and full-synthetic media of
AMSOIL Ea Motorcycle Oil Filters allow them to provide
unmatched performance in motorcycles and other
power sports equipment. EaOM Filters last longer, stop
smaller dirt particles and offer less restriction than other
filters. Ea Motorcycle Oil Filters provide filtering efficiency
of 98.7 percent at 15 microns, outperforming the best cellulose/synthetic blend media on the market. For maximum engine protection, AMSOIL recommends changing the EaOM every time you change oil.
Superior Alternative, Multiple Applications
AMSOIL Ea Motorcycle Oil Filters provide unsurpassed
protection for motorcycles, ATVs, four-stroke personal
watercraft, four-stroke snowmobiles and four-stroke
outboards. AMSOIL is producing an initial offering of 16
Ea Motorcycle Oil Filters manufactured for the most
popular power sports applications. Eight of the 16 filters
are chrome plated.



Applications
AMSOIL Ea Motorcycle Oil Filters provide superior oil filtration
for Motorcycles and Power Sports Equipment. Note: the C at the end of the EaOM filter name means the filter is chrome.
