How does AMSOIL , Oil-Wetted Gauze like K&N and Paper Air Filters Compare in Industry Standard Testing?
Here’s a more detailed test procedure and conclusive results covering AMSOIL vs. K&N and paper air filters according to the Industry Standard Society of Automotive Engineers (SAE) test standard SAE J726. Your car’s engine “inhales” air that is mixed with fuel for combustion. But air contains an incredible amount of suspended dirt – typically 400 tons of it in a cubic mile. Much of this is microscopic dirt, extremely abrasive, that can cause serious damage inside the engine. Consequently, an air filter is a necessity. It provides the engine’s first line of defense against air-born dust. An air cleaner must not only trap as much grit as possible, but it should do so without “smothering” the engine, restricting its vital airflow. Thus the most desirable performance characteristics for an air cleaning device are high dirt-trapping efficiency, and minimal airflow restriction as the dirt accumulates. The Society of Automotive Engineers Test Code J726 specifies the procedures, conditions, equ
