Amsoil Video on their New Absolute Efficiency Air Filter
AMSOIL Ea Air Filters (EaA)
The Absolute Best Air Filtration Available for Cars and Light Trucks.
Guaranteed for 4 Years or 100,000 miles
AMSOIL Ea Air Filters represent a major breakthrough in filtration technology. The revolutionary
nanofiber technology used in AMSOIL Ea Filters captures more dirt, holds more dirt and allows
better air flow than conventional air filters. AMSOIL Ea Filters improve engine performance and
help engines last longer.
AMSOIL Ea Air Filters
are the most efficient filters available to the car/light truck market. Ea Air Filters’ synthetic
nanofiber media removes 5 times more dust than traditional cellulose filter media alone and 50
times more dust than wet gauze filter media. AMSOIL Ea Air Filters have a service life of 100,000
miles or four years, whichever comes first.
Amsoil EAU Air Filters for After Market Air Intake Systems
Ea Air Induction Filters (EaAU)
AMSOIL now offers universal air induction filters (EaAU) designed
to replace stock oil wetted gauze or foam conical filters that were supplied with custom
induction systems. AMSOIL Ea Air Induction Filters offer better efficiency, excellent airflow
and are cleanable.

More Cold Air = More Horsepower
The basic purpose of the air intake system is to bring cool air from outside the engine
compartment into the engine. The cooler air is denser than the air found within the hot engine
compartment. The denser charge contains more oxygen than warmer air, providing better combustion
through a more effective air/fuel mixture.
Another advantage of most specialty-equipment cold air intakes is their consistent diameters and
the absence of sharp bends, both of which help to eliminate turbulence in the air stream.
EaAR Air Filters
AMSOIL EaAR Filters are specially designed for racing and street rod enthusiasts who desire
AMSOIL Ea protection in carbureted applications. AMSOIL EaAR Air Filters are constructed with the
same synthetic nanofiber media as other AMSOIL Ea Air Filters.
AMSOIL custom EaAR Filter assemblies are designed for racing applications. They
incorporate good looks and excellent air flow in addition to the high efficiency afforded by AMSOIL
Ea nanofiber technology. These custom air cleaner assemblies are designed for use with carbureted
engines that use a 14-inch round element air cleaner housing. AMSOIL EaAR kits provide more air
flow than competing assemblies. The kits feature the common 14-inch diameter carburetor plate, air
filter and high air flow lid along with a two-inch, three-inch, four-inch, five-inch or
six-inch-high filter. Replacement filters, air flow lids and carburetor plates are also sold
Ea Air Flow Lids
AMSOIL EaAR Filter kits provide racers with more power through the new Ea air flow lids. The air
flow lids are constructed using AMSOIL Ea nanofiber media, adding filtration area. They feature a
polished aluminum trim ring with AMSOIL logos etched on the surface. Not only do the Ea air flow
lids add filter area, they actually redirect air inside the filter to pull in more air through the
side pleats for even greater performance efficiency.

AMSOIL now offers Ea Pre-Filters (EaPF) for racing and off-road
applications. AMSOIL Ea Pre-Filters prevent large particles from sticking to EaAR and EaAU Filters
and blocking the flow of air.
What Are Pre-Filters?
Ea Pre-Filters fit over the top of existing air filters. These polyester mesh bags feature an
industrial grade elastic band at the opening to ensure the pre-filter does not slide off.
Why Use Pre-Filters?
Racers and off-road enthusiasts subject their vehicles to some of the most severe conditions
possible. These vehicles operate in areas of heavy dirt and mud that gets slung into every crack
and corner, often clogging air filters. AMSOIL Ea Pre-Filters are designed to keep larger particles
from getting into and clogging the pleats of air filters. When an air filter is clogged, the engine
loses horsepower and, in the case of Ea Air Filters, the filter must be cleaned. There is no vacuum
or compressed air available on the race track or out in the swamp, but an Ea Pre-Filter is easily
removed and shaken free of debris in seconds.
Ea Motorcycle Air Filters
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.
Donaldson Endurance™ Air Filters for heavy duty
Donaldson Endurance™ air filters deliver cost-saving
• Longer Engine Life
• Longer Filter Life
• Ideal for Extended Maintenance Intervals
• Double Mileage Guarantee
Donaldson Endurance Cross Reference
Donaldson Endurance™ Air Filters with exclusive nanofiber technology offer longer engine
life, longer filter life, initial efficiency up to 99.99 percent and five times more capacity.
The nanofiber technology causes submicron contaminants to be held on the surface layer of
smaller fibers. This filtration characteristic is only possible with this new type of air
filtration technology. In on-highway applications, where the contaminant is primarily submicron in
size, Donaldson Endurance filters cause less restriction than conventional filters with cellulose
media. The smaller interfiber spaces of nanofiber technology have a higher efficiency and capture
