What do you like about WIX/NAPA?
What's not to like, I run NAPA/Wix filters on all my vehicles.
I Preface this by: myself being an Engineer and engine builder with no" Fan Boy-isms" or " My Choice - take a hike" mentalities
1) In the smaller sizes, the base -end bypass assembly ( great design, BTW ) takes up too much real estate from the
filter paper available surface area; with the new Asian brand cars using tiny "fuel filter" sized oil filters - this is a BIG issue.
Another thing about the WIX/NAPA Gold filters with the base end bypass is that there is only a thin area of just metal-to-metal contact where it seals on the filter cartridge end cap. Could be why their efficiency is in the 95% @ 20u point. Motorcraft filters with the base end bypass have a better sealing design IMO.
I've used the normal WIX/NAPA Gold filters, and they are nicely built, and the efficiency is OK.
