On LS1 and other boards, I have read where the AC Ultraguard golds were one of the best oil filters. However, I have not read much about them here.
What does everyone think about them?

Who says they were discontinued? I know Pep Boys stopped carrying them, but I order mine online directly from AC Delco. Besides that, all the product technical specs are still up at acdelco.com.quote:

Well, they aren't all gone, they still make the UPF44, the tiny stock filter for the LS1, but I feel this filter is way too small for an engine with such a large oil capacity (especially in the Vette with their 7 quart oil pan!)
Unfortunately it is indeed true. I emailed AC Delco and they sent me a response back, which I saved, but it's on my home computer. They say they weren't selling well enough, but due to overwhelming demand (from C5 owners) they are continuing to make the UPF44 filter.quote:
