Advanced Performance (AP) Oil Filters use a media that is rated at a Frazier air flow of approximately 267 CFM and is wire-backed. The unique wire-backing provides a very stable base for a media blend of fiberglass, polyester and cellulose. This media is resistant to high temperatures and water levels in the oil that can plug standard media types. Our Advanced Performance media is designed to provide a high positive oil flow with low restriction.
High Efficiency Endurance (HEE) Oil Filters use a media rated at a Fraizer air flow of approximately 75 CFM. This media contains a higher resin content than our Advanced Performance Filters to trap and hold smaller contaminant's and provide higher efficiency.
