I have been using NAPA Gold filters (made by WIX) in everything in our stable for some time now. Yesterday I stopped by my local NAPA to pick up a NAPA Gold filter for my Honda, only to find out it was no longer avaialble. I ended up with a NAPA Powersports filter, since I needed to change the oil. I had kept the lid off the old filter box for reference, so when I got home, I pulled it out to see what part number it had. Low and behold, it was the same number as the Powersport filter, but without the PS prefix?
Later I happened to be back at NAPA picking up some parts for my son and I told the counter guy what I had found. He replied that after I had left, he called corporate to see what was going on. I turns out that NAPA is dropping WIX as a supplier in favor of different (which I assume means lower cost) suppliers for various filters.
It looks as if I'll have to see who ends up making what before I purchase more filters in the future.
