When you finally find out how to replace it, think about replacing it with an air filter that will go 100,000 miles or 4 years before it needs replacing again.

90163Absolute Efficiency AMSOIL Ea Air Filters are the most efficient filters available to the car/light truck market. Ea Air Filters' synthetic nanofiber media removes 5 times more dust than traditional cellulose filter media alone and 50 times more dust than wet gauze filter media. AMSOIL Ea Air Filters have a service life of 100,000 miles or four years, whichever comes first.
Better Air Flow AMSOIL Ea Air Filters allow more airflow than filters that use cellulose media alone. Cellulose fibers 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, which results in higher restriction and less capacity. The synthetic nanofibers in EaA Filter media have submicron diameters and small interfiber spaces, which result in more contaminants being captured on the surface of the media and lower restriction.
