Filtration

The AMSOIL Ea filter line has given AMSOIL the same top-tier standing in the filtration market that it has always enjoyed in the lubrication market. Ea stands for "absolute efficiency," and these revolutionary filters use nanofiber technology to provide the best filtration available today. Along with Ea filters, AMSOIL offers filtration products from Donaldson, WIX and Twin Air to cover nearly every filtration application possible.

Air Filters

AMSOIL Absolute Efficiency Air Filters (EaA) provide the absolute best air filtration available for cars and light trucks. They are recommended for four years or 100,000 miles, whichever comes first, and are easily cleaned every 25,000 miles with a vacuum or air compressor.

AMSOIL Absolute Efficiency Air Induction Filters (EaAU) are designed to replace stock oil wetted gauze or foam conical ilters that were supplied with custom induction systems. They offer better efficiency and airflow, and they are cleanable.

AMSOIL Absolute Efficiency Racing Air Filters (EaAR) are specially designed for racing and street rod enthusiasts who desire AMSOIL Ea protection in carbureted applications.

AMSOIL Absolute Efficiency Pre-Filters (EaPF) Designed for racing and off-road applications, these pre-filters prevent large particles from sticking to EaAR and EaAR filters and blocking the flow of air.

AMSOIL Absolute Efficiency Crankcase Breather Filters (EaAB) provide excellent oil vapor control, increased efficiency and better engine performance in street rod and racing applications. They are a perfect complement to EaAR racing filters.

Oil Filters

AMSOIL Absolute Efficiency Oil Filters (EaO)feature advanced full synthetic nanofiber technology, making them the highest efficiency filters available for the auto/light truck market. They are guaranteed for 25,000 miles or one year, whichever comes first, when used in conjunction with AMSOIL Synthetic Motor Oil in gasoline and diesel engines in normal service.

Motorcycle Filters

AMSOIL Absolute Efficiency Motorcycle Air Filters (EaAM) bring nanofiber technology to the motorcycle market with filters that hold 15 times more dust than a wet gauze type filter.

AMSOIL Absolute Efficiency Motorcycle Oil Filters (EaOM) provide unsurpassed protection for motorcycles, ATVs, four-stroke personal watercraft, four-stroke snowmobiles and four-stroke outboards. These filters come in black and chrome plated finishes.

By-Pass Filtration

The Ea By-Pass Oil Filter (EaBP) provides the best possible filtration protection against wear and oil degradation. Working in conjunction with the engine's full-flow oil filter, the AMSOIL Ea By-Pass Filter operates by filtering oil on a "partial-flow" basis. It draws approximately 10 percent of the oil pump's capacity at any one time and traps the extremely small, wear-causing contaminants that full-flow filters can't remove. The AMSOIL Ea Bypass Filter typically filters all the oil in the system several times an hour, so the engine continuously receives analytically clean oil.

The AMSOIL By-Pass Oil Filtration System provides dramatically extended drain intervals, improved oil cooling, increased filtration capacity and life, increased fluid system capacity, efficient small particle and soot removal, significantly extended engine life and increased engine efficiency.

The AMS-Oiler Oil Precharger (AMK) puts an end to potential dry-engine starting.
