It uses cellulose media to trap contaminants down to 25 microns with 99% efficiency, protecting injectors and pumps from wear. Designed as the first stage of a two-filter system, it captures larger particles before the secondary filter, helping to prevent fuel starvation and maintain optimal engine performance. It is typically replaced at regular maintenance intervals to avoid clogging and ensure clean fuel delivery.
