Product Description
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.
Large and Growing Market
According to research done by the Specialty Equipment Market Association (SEMA), a new air intake system is among the first modifications a consumer makes to his or her vehicle. Since changing the air filter alone cannot eliminate air restriction built into the vehicle at the factory, replacing the factory air flow assembly includes replacing the filter, air box and air path. SEMA reports sales of air intakes are over 300,000 every year.
While intake kits were initially sold only for performance-type applications, they are now also being marketed and used as a way to boost fuel economy in SUVs, minivans, trucks and more.
AMSOIL EaAU
AMSOIL Ea Air Induction Filters fit most of the popular intake systems available. They provide improved cold air intake and a level of engine protection only an Ea Filter can provide. AMSOIL is currently offering nine Ea Air Induction Filters with varying lengths and widths. These filters have flange IDs of 3", 3.5", 4", 4.125", 4.5" and 6". Since these filters offer a universal fit, AMSOIL provides the dimension sheet below that customers can use to determine the proper filter for their applications.
Cleanable
AMSOIL Ea Air Induction Filters are cleanable and long lasting. AMSOIL recommends cleaning the Ea Air Induction Filter when designated by the restriction gauge if the vehicle is so equipped, or according to operating conditions. If it is used in extremely dusty environments or in a performance vehicle, more frequent cleanings may be required.
Unique Design
To increase filter surface area and the volume of air entering the engine, the top of many popular Ea Air Induction Filters (EaAU) is cut away. The media is inserted in a conical form pointing toward the direction of airflow.
Quality Construction
AMSOIL Ea Air Induction Filters are made from the same high-quality nanofiber media found in other AMSOIL Ea Air Filters. The nanofiber media is pleated with epoxy-coated wire on the face and back of the media for additional strength and stiffness. High quality, pliable urethane connectors with plastisol potting complete the product. Each Ea Air Induction Filter comes with a clamp for convenient installation.

Power gain was better than exhaust upgrade
I was always reluctant to use a oiled foam or K&N filters to gain few extra ponies, as they allowed lots of dirt along with more air. Sending dirt to the engine via coarse air filter increases engine wear (expensive mistake).
So amsoil's nano technology was the answer. I upgraded along with a duct work to suck in fresh air (cold air intake). The upgrade gained lots of power throughout the rev range. I noticed considerable torque improvement at lower rpm's allowing me to continue in the same gear while going up hills.
This upgrade brought forth much better performance gain than the expensive custom made exhaust system I installed.
