I have used wix gold filters forever and had good luck. In the last year or so I ordered the wix select filters for my daily drivers and a fleet of class 6 trucks I work on. They are no longer made in USA and come from all over the place now. So I order a couple Wix gold for my Buicks and one is made in USA and looks the same as all others I have had (51040) and the other is made in China and physically looks different. I don't care if companies ship production off shore to save money but now I am paying premium price for sub par junk. Just passing it on.
