Didn't GM change the bypass requirements recently? Does Purolator make new filters with the new bypass setting?

Because Wix does. And they even offer XP versions, too

I'm using an early Fram Ultra on my Duramax and it works just fine.
 
Yeah, Purolator shows me they have no faith in their "made by" i.e. "jobber" filters. I'll trust ULTRA filter before any Puro

Ultras can make things worse, depending on application. ...
