It uses cellulose media rated at 25 microns efficiency to trap dirt and wear particles while allowing full oil flow to engine bearings and components. A built-in bypass valve opens if the filter becomes clogged or during cold starts, ensuring your engine never runs dry. You would replace this filter at every oil change interval to protect your engine from premature wear and maintain proper oil pressure.
