Oil Filters - consumer vs pro

[torrmundi]

I have autopsied 3 filters in the interests of science (and cruisers). All are, I am told, made by Wix: a ProTec, a Carquest, and a Wix.


The ProTec and the Carquest are remarkably similar, and the Wix is substantially similar. The former have 52 pleats, stamped springs, and simpler rubber valve diaphragms. The Wix had a more expensive coil spring, 44 pleats, gussets in the rubber diaphragm.



From appearances, I can't see justification for buying the more expensive options. Perhaps there are performance differences, but until that is shown publicly, I will make economic choices.
