I need to replace my Sta Rite filter cartridge # WC108-57S2X. The original has a open interior with out a slotted plastic sleeve. The generic replacement has a slotted interior sleeve . Will that slotted sleeve restrict water flow through the cartridge resulting in excess pressure and diminished filtering?

HI. It will not. You will not see an increase in filter pressure or restricted water flow.
