Replace your air filter with Nanofiber!  Introducing the Absolute Efficiency Air filter
Amsoil EaA Filters

Ea Air Filters represent a breakthrough in air filtration technology. The amazing nanofiber filter material used in AMSOIL Ea Filters captures and holds more dirt and permits better air flow than ordinary air filters. AMSOIL Ea Air Filters increase performance and help engines last longer. The filtration medium used in the Amsoil Ea Air Filter was originally developed for the M1A1 Abrams tank, for superior filtration in the dustiest environments and easy servicing in the field.  This revolutionary filter has been brought to the market by Amsoil first, completely obsoleting the wetted gauze and oiled foam aftermarket filters available from other companies.

Absolute Efficiency
AMSOIL Ea Air Filters are by far the most efficient filters available on the market. Ea Air Filters’ synthetic filtration media removes 5 times more dust particles than ordinary cellulose filters and 50 times more than wetted gauze or oiled foam filter media. AMSOIL Ea Air Filters are guaranteed for 100,000 miles or four years, whichever comes first.

Amsoil Universal Filter Applications

Ea Air Induction Filters

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 produced by K&N, Injen, S&B, Green, AIRAID, AFE, TrueFlow and more. AMSOIL Ea Air Induction Filters offer better efficiency, excellent airflow and are cleanable.  Gauze and foam filters sacrifice filtration for flow, so in order to gain a few horsepower you have to let a lot of contaminants into your engine, which eventually end up in your oil and can lead to accelerated wear.  Amsoil EaA filters get you the improved flow without forgoing effective filtration.  In fact, they filter BETTER than regular paper filters.

Isn’t this a lot more expensive? I want to save money, not spend more!

Amsoil Ea Air filters are guaranteed for 100,000 miles or four years. Once per year you just clean it by gently vacuuming it, or blowing it off with low-pressure air. If you replaced your regular paper-element air filter once per year like you're supposed to, the EaA filter pays for itself in the 3rd year. If you've been using an oiled gauze cone filter or an oiled foam filter, you save with an EaA filter because you don't have to buy a cleaning kit. There's no cleaner needed, and no oil to apply.


How about OEM fitments?

Absolutely! Amsoil makes an Absolute Efficiency - Air (EaA) filter to fit most cars on the road today. Just use the online application guide at the Amsoil website to find the filter that fits your car.  While you're there, pick up some oil and an oil filter and discover what premium synthetic oil can do for you and your car (think 12-month change intervals).

EaA stands for Absolute Efficiency - Air, and the name comes from the fact that Amsoil's nano-fiber technology filter is 5 times more efficient at 0.8 microns than paper, and 50 times more than wetted gauze.  That means it removes 50 times more dirt and dust from the intake air.  While filtering better, it also flows far better than paper, and doesn't clog up over time. Compared to gauze, EaA flows almost as well when clean, and doesn't flows less and less as the filter media loads up, like gauze or foam.
