Napa carries wix filters that are made for napa that are supposedly the same as the wix branded of any given number. However, they have 2 versions with the SAME number except for the first number which they say denotes the oil change interval. The filter i use comes in those 3 versions starting at around $6, then $16, then $24. As I said, I was told the different versions are for different oil change intervals. HUGE difference and what i am curios about is are they all the same as far as performance with the only difference being the more u pay the more area in the filter to hold debris? Or is the performance also lesser? The sales guy, and he IS a sales guy after all so who knows, but he said they will all perform the same except that the less cost ones must be replaced sooner. Do u believe that or have reasons to believe different?
Now i realize no one can answer this unless you have done some serious research of your own or read papers on it or whatever. So i don't expect a truly informed anser but i AM hoping someone here does have that one way or another.
