The 6I2507 Primary Element contains a spool insert which makes the element more rigid. This spool helps prevent the element from collapsing when the pressure drop across the element is high. The pressure drop across the element increases as the element becomes plugged.
Never mix radial seal and axial seal primary and secondary elements in the same air cleaner. Never use the 6I2508 Secondary Element with the 6I2505 Primary Element.
