The info I got was, NAPA does not make filters, they buy them from cheapest bidder. So you may get a STP filter this trip and next time it might be a Fram or something Chinese.
The TYMAR is a Donaldson I think, and has the highest water displacement value of any filter on market. That probably doesn't mean anything to most of, unless you are off roading in creek or driving down interstate behind tractor trailer during down pour. Some people have had trouble with the 6637 poping off the tube on homemade set ups, as well as cheese grater efect on fender well insulation.
Call Dale at TYMAR he will give you the exact facts.
