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 eaais 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 nanofiber technology used in AMSOIL Ea Filters surpasses all other technology in efficiency, capacity and service life. With AMSOIL Ea Filter, dust and submicron particles remain on the surface and are trapped on top of 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.
