Filters
Bob-
NAPA Gold Filters are Wix. Just with a different silk-screen. After shucking parts for years through college (At a few parts stores, and not too long ago) and seeing some of the promo demos at SEMA in Las Vegas, they're the ONLY filter I use. A Purolator rep came in when I was selling filters, and cut open a Wix, Fram, Delco, Motorcraft, and of course Purolator and PURE-ONE Purolator filter for comparison. Shocking what's inside those Fram's isn't it?
Delco's used to be OK, but now each P/N uses sub-suppliers, I don't know where the PF-141's come from, but they look identical to the Purolator cartridges.... (Which are still better than the CH-200PL Fram's)
Wix makes about 80% of the private label car-parts brand filters (I know they make CarQuest, Parts Plus, and Napa Gold for certain).
Just food for thought... It might save you some travel time, cash, and convenience...
