I am running one, I just put it on about a week ago. It will be on for at least 6 months, and then I will have comments when I cut it open. I did cut open a AC Delco Ultraguard Gold for the same application recently and it is the same material at the Royal Purple filter and made by Champion Labs also, with one less pleat and it looked good (meaning all pleats looked the same as they do when new, just covered with oil now).
