It uses cellulose media to capture particles down to 9 microns at 99% efficiency, protecting injectors and pumps from wear. This filter is typically replaced during scheduled fuel system maintenance, usually every 10,000 to 15,000 miles or as recommended by the engine manufacturer. A clogged or overdue filter can cause power loss, hard starting, and injector damage.
