We’ve sold 100’s of these often as the result of another testimonial. It’s a simple match fit to your existing intake system. Amsoil PreFilter cover is optional. Mileage and throttle response improves noticeably especially tors the end of the cleaning cycle.
Research will show you how nanofiber is superior in performance, engine protection and cost over all over mass produced filtration products on the market. It’s the material used in hard drives and clean rooms.
Our #1 best selling size (see cross reference chart below) is our K&N RU-3570 replacement which is the Amsoil EAAU3050. Most notable replaces the low capacity K&N filter which fits: 69 Series Typhoon air intake systems for Honda Accord, Scion and Dodge Caliber.

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.
To boost airflow into the engine, the tops of EaAU Filters are cutaway. The media is inserted in a conical form that is oriented toward the direction of airflow. This configuration increases the surface area of filtration, which increases airflow through the filter for optimum power.

Filter More Contaminants
EaAU Filters are made from high-quality nanofiber media. In lab testing, the nanofiber media found in EaAU Filters removed 5X more dust than the average cellulose filter and 50X more dust than the average wet-gauze media, delivering excellent protection against wear-causing contaminants entering the engine. Again – holding it over a light-bulb – the oil wetted gauze is covered in significant holes. Not a good idea!
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. The difference is AMSOIL offers the customer a filter which offers the complete rating and the only nanofiber glass media which prevents particles from lodging in the filters.
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″ and 4.5″. 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.
In laboratory testing the nanofiber air filters removed 5 times more dust than the average cellulose filter and 50 times more dust than the average wet gauze media. (Efficiency)
Nanofibers held 15 times more dust than average wet gauze type filters and 2.5 times more than OEM filters. (Capacity)
The EaAU air filter will provide all the needed flow you will ever need! It will allow more high flow with less restriction over time than any competitor filter – wet or dry!
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. Only takes about 15 PSI or shop-vac to clean.
AMSOIL Ea Air Induction Filters are made from the same high-quality nanofiber media found in the carburetor series 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. EaAU Filters are designed to withstand the severe operating conditions common to high-performance vehicles.
Nanofiber is a phrase generally referring to a fiber with a diameter less than one micron. Cellulose fibers, on the other hand, are larger than nanofibers and have larger spaces between the fibers, causing contaminants to load in the depth of the media and plug the airflow path, resulting in higher restriction and less capacity.
AMSOIL Ea Air filters incorporate a specially constructed cellulose media with exclusive synthetic nanofibers applied to the surface. Dust and submicron particles are trapped on the nanofiber surface, preventing them from lodging in the filter media depth.
Here’s how it works: Imagine two filtration media, a chain link fence and a mosquito net. Each is required to stop contaminants, in this case tennis balls.
A tennis ball will fit quite nicely into an opening of a chain link fence, but will obstruct the hole almost 100 percent. Now, imagine a tennis ball covering a mosquito net. The tennis ball, at the point of contact with the netting, will obstruct much less filter area than the chain link fence example. In fact, air will flow around the tennis ball all the way to the point of contact. It will take many more particles to obstruct the netting surface area than the chain link fence.
To add to this, dirt is easily shaken off from normal engine vibration. These filters are simple to clean using low pressure compressed air or vacuum. As of now there is absolutely no reason to replace your cold air intake filter with wetted gauze types such as K&N, Airaid, Fram, AEM, Injen, and more. Perhaps take an oil sample with our analysis kits before and after and see the contaminants you filter is allowing into your engine (and you are paying a lot of $ for that filter.)
EaAU Filters are cleanable and long-lasting. Clean the EaAU Filter when designated by the restriction gauge if the vehicle is so equipped, or according to operating conditions. If the EaAU Filter is used in extremely dusty environments or in a performance vehicle, more frequent cleaning may be required. Clean with low-pressure shop air or vacuum. Change EaAU Filters every four years or 100,000 miles.
Note EAAU4095 and EAAU4178 both have sensor ports at the top of the unit.

Air Filter Basics
An engine needs air in order for combustion to occur, 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 are the leading cause 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 the more contaminants the filtration media holds, while still allowing optimum air flow, the better the filtration media is.
The new 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 which extends engine and filter life and reduces engine wear.

Another new product offered for street rods: AMSOIL racing filters for carbureted engines as well as crankcase breather systems. Kits available in various heights 2″, 3″ 4″ 5″ and 6″. Click on the photo for details.
We found this note on one particular K&N replacement filter:
Look what K&N says: K&N HIGH FLOW UNIVERSAL AIR FILTER, RED — Racing use only; Not applicable nor intended for use on emission controlled street or highway vehicles; 96 to 99 percent filtration efficiency. (99 percent efficiency at what micron?? They don’t expect you to ask that question. Any filter is 99% efficient at 80 or maybe 60 microns but only AMSOIL can say 98% at 2 microns.)

Mitsubishi Lancer Evolution
Here’s a review from the Mitsu Evo forum using the AMSOIL EAAU4560:
“I found out the new Amsoil filter spools the Turbo faster at low rpms, and in the mid range, it made more peak boost. It also maintained the boost more the higher the rpms. Using the super AFC-II, the new Amsoil Filter logged 2276 Hertz at peak boost, and the Injen did 2145 Hertz.
That means that the Turbo was able to suck 130 plus more Hz and feed more air into the engine.”
The EAAU4560 replaces the popular K&N-RU3480
