I used to use Wix, not any more since Mann owns them. Quality has gone down.
Last winter the filters developed leaks from the gaskets on 3 of my vehicles. 2 3.6 V6's and the 5.3 in my Tahoe. They were seeping oil and I had to super crank them down to stop the leak in-between oil changes. I now use UPF AC filters with no issues.
