I also use Wix filters , best filter on the market IMO .

I use either NAPA Gold or Wix depending on where I buy the filter.
I've been told Wix makes the NAPA filter. My preference has a lot to
do with the threading. The base of Wix filters is punched and
threaded into the body of the filter and I find it easier to start
than the brands that are punched outward, if that makes any sense.


Â*Â* Makes sense to me . In fact , Wix makes NAPA Gold filters . IIRC
the Wix number for your Evo (and some Shovelheads) is a 51215 , the
NAPA Gold is 1215 . Back around 1999 or so some guys on the XL-List
cut up a bunch of filters to see how they compared . Fram was the
cheesiest with the least and thinnest filtration medium . Wix won over
all , and I haven't used anything else since .


Throughout the years, I have often seen comparison videos of oil filters
and Fram continuously ends up at the bottom. Wix, Mobile 1, Bosch,
Purolater usually on top as well as a few others depending who's doing
the test and what model filter.

But have you ever seen any actual performance tests that indicate the
visual comparisons have any relevance to actual filtration performance
and resultant demonstrably better engine performance in terms of fewer
oil contamination or other failures even remotely that could be
demonstrated as owing to the filter?

Oil related engine failures are so rare it would be hard to really
make any kind of comparison. I know people, mostly single mom types,
who never change their oil and they end up throwing the car away for
things other than an engine failure. The oil looks like tar but it
still seems to be working.
