AMSOIL Ea Motorcycle Air and Oil Filters

Second to None Air and Oil Filtration for Your Motorcycle

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 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 sub-micron 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.

AMSOIL Ea Motorcycle Air Filters

The filtration media in the AMSOIL Ea Motorcycle Air Filters 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 contaminats 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 carfully 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.

Superior Alternative - AMSOIL is producing Ea Motorcycle Air Filters for the most popular Harley Davidson models from 1988 to the present, including motorcycles equipped with S&S carburetors and air cleaner housings.

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.

AMSOIL Ea Motorcycle Oil Filters

AMSOIL Ea Motorcycle Oil Filters feature a specially constructed silicone anti-drainback valve and a nitrite 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 Ea Motorcycle Oil Filters manufactured for the most popular motorcycle and power sports applications.

AMSOIL Synthetic Motorcycle Oil Articles and Testimonials


Premium AMSOIL Synthetic Motor Oils offer the longest drain intervals on the market, unsurpassed protection and performance that effectively extends equipment life and improved fuel economy, saving customers money at the pump and reducing the nation’s dependence on foreign oil.


"AMSOIL INC. warrants that the use of its lubricants will not cause mechanical damage to any mechanically sound equipment when AMSOIL INC. products are used in full compliance with the company's recommendations and instructions."


FULL WARRANTY


AMSOIL synthetic motor oils are formulated to surpass engine test specifications, offering protection far greater than competing motor oils for extended drain intervals. Most synthetic oil manufacturers make no claim to extended drain intervals, deferring to the maintenance schedule provided by the vehicle manufacturer. With its unparalleled oil and warranty program, AMSOIL offers consumers unprecedented protection and economics.


Another AMSOIL First

More than 20 years ago, AMSOIL began using the NOACK volatility test as a comparison tool and measurement of quality. Back then, nearly every oil tested side-by-side with AMSOIL synthetic motor oils failed, and those that passed barely squeaked by. Other oil companies paid no attention to NOACK results until Ford Motor Company made it a requirement for service fill oils, validating what AMSOIL had said all along.


THE NOACK Volatility Test
The NOACK Volatility Test determines the evaporation loss of lubricants in high temperature service. The more motor oils vaporize, the thicker and heavier they become, contributing to poor circulation, reduced fuel economy and increased oil consumption, wear and emissions. AMSOIL Synthetic Motor Oil resists high temperature volatization better than other motor oils. AMSOIL Synthetic Motor Oil maintains peak fuel efficiency and reduces oil consumption and emissions.
