The filter set is sold as a direct replacement. I'd rate them at 'B' on that. The exit ports on both filters were not a match to the manifold size in the filter housing. It took some doing to find o-rings of the right size to seal the junction. Oddly, one port was too big, and one was too small. Also, after 60 days of use, the retention straps on one of the filters are already dislodged. I'm not sure if that is important or not.

My old original System 3 filters are still working fine, but after 17 years of hard use and a yearly cleaning with a power washer I felt it was time to retire them.
