AMSOIL
Air Induction Filters

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. Cleaning AMSOIL EaAU Filters requires no oiling or soap and water, simply clean with low-pressure shop air or vacuum. AMSOIL recommends changing EaAU Filters every four years.

Unique Design
To increase filter surface area and the volume of air entering the engine, the top of the Ea Air Induction Filter 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.

Designed to Provide More Air Flow
EaAU filters are designed to provide more air flow than aftermarket gas or diesel intake kits can demand. The graph at the right illustrates the flow characteristics of one of the smallest and one of the largest AMSOIL EaAU Filters, the AMSOIL EaAU 3050 and EaAU 4090. Tests were run to appropriate application demands, not to filter capacity. This example ses a stock 5.0L Mustang that requires 200 CFM at 3000 RPM, which is near peak HP performance. After installing the largest aftermarket intake system available, the Mustang only requires 300 CFM at 3000 RPM. The EaAU 4090 is still only drawing two inches of restriction and continues to allow more air flow than the engine can handle. Even the EaAU 3050 is only drawing three inches of restriction and still allowing more air flow than the engine can handle.

AMSOIL EaAU filters are designed to replace air induction filters on a dimensional basis only. EaAU filters do not provide connections for engine sensors found on some aftermarket induction system filters.
