EA Air Filters

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.

Nanofiber Basics

Because the nanofibers in AMSOIL Ea Motorcycle Air and 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.

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 sealing area.

Superior Filtration

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.

Cleaning Instructions

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.

My own past bikes include a '98 Guzzi EV1100, and
a '98 Honda Magna V4.

EA Oil filters

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.

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.

OEMs Inflate Prices on Inferior Products

Original equipment manufacturers (OEMs) typically recommend their own brands of motor oils and lubricants for their equipment.
Consumers believe those “brandname” lubes are the best for the motorcycles, snowmobiles, ATVs, outboard motors and other recreational
equipment they buy. “Consumers often operate under the premise that the manufacturer not only knows what’s best for the equipment but also provides the best,” said Dave Anderson, AMSOIL technical product manager. “Their impression is that the OEM oils are always the best, and in many cases
nothing could be further from the truth.” Anderson has more than 25 years of experience at AMSOIL and has conducted numerous comparison tests throughout that time. Consumers falsely assume OEMs actually manufacture the oils and lubes that carry their brand name. However, OEMs typically buy lowcost and sometimes low-quality oils
from lubricant manufacturers, put their labels on them and send them out for distribution at dealerships. “Manufacturers can command higher prices simply because the consumer perceives it to be more appropriate for the application,” Anderson said.
Contrary to consumer perception, research indicates OEM lubes often aren’t equal to the performance quality of the cheapest aftermarket oils on store shelves. “Manufacturers probably do know more about the equipment,” Anderson said. “If indeed they know what’s best for their product, their lubricants should outperform – or at least meet the performance levels of – the other products out there. But results show that in most cases
OEM oils were inferior to others.”
 

The ASTM D-4172 4-Ball Wear Test determines an oil’s ability to minimize wear in case of metal-to-metal contact. Four steel balls are placed in the test oil with one held in place and rotated under a prescribed load and temperature against the other three. After a one-hour period of constant load, speed and temperature, the lower three balls are inspected at the point of contact. Wear appears as a single scar on each of the balls. The lower the average scar diameter, the better the wear protection of the oil. As seen in the graph, AMSOIL
20W-50 Synthetic Motorcycle Oil (MCV) offers significantly better wear protection than competing OEM motorcycle oils.

The High Temperature/High Shear Test measures an oil’s viscosity (thickness) at high temperatures under shearing forces. Shear stable
oils that are able to maintain high viscosity at high temperatures perform well in the HTHS Test. The test combines viscosity, shear stability and viscosity index. It’s important because bearings require the greatest level of protection during high temperature operation. The higher the test result, the greater the level of protection offered by the oil. As seen in the graph, AMSOIL 20W-50 Synthetic Motorcycle Oil (MCV) significantly outperformed competing OEM motorcycle oils in HTHS testing.
