It uses synthetic Synteq media to remove 99% of contaminants down to 5 microns, capturing dirt, rust, and water that can wear injectors and cause power loss. Regular replacement helps maintain proper fuel flow, combustion efficiency, and prevents costly downtime. It is commonly used as a direct-fit secondary filter on Cummins ISX and X15 engine platforms.
