You may want to give another filter manufacturer's website that has cross-referencing a try. I know the Wix website provides all the specs/dimensions for their filters. Find out the corresponding Wix part #'s for the PF44 and PF46, and go from there. My wife's car calls for a PF44, so maybe I'll try that myself. This is the first I've heard of it. L8R

Wix's website gives the same cross reference for both of those numbers though, they give the 51042. This is why I suspect the filter size is identical but AC Delco just changed the filtering media. (both filters have antidrainback valves and neither has a bypass valve since GM engines have them built into the block) I sent an email to Dana, who make the AC Delco filters for Canada, so hopefully they'll shed more light on it.

At some point over the last year or so, AC Delco has stopped making the PF44 and has replaced it with the PF46. Does anyone here know exactly what the differences are?

Interesting ...... the PF46 is listed for all 2004 vehicles using this application (i.e. Corvette). Same applications listed the PF44 for the previous year(s). GM still sells the UPF 44. I thought that one was kept alive specifically for Corvette owners. I wrote an e-mail to AC Delco ...... let's see what they say in regards to the PF44/46 .......

Does anyone have the GM part# for the UPF-44 filter. I'm trying to order some from "GM Parts Direct" and they need the GM part#.

VQ35DE, Thanks for the AC #. That's exactly what I was looking for. By the way, we're almost neighbors, I live in Buchanan, Tn., near Ky. Lake, about 45 miles from Union City. The reason I'm looking for the UPF-44 (or 46) is that I bought a new, redline red, Chevrolet SSR last Fri. and the owners manual calls for the PF-44 oil filter. I plan to drain the factory oil at 1,000 miles and replace with UPF filter and Mobil I. Thanks again.

pharmer, Your correct, Buchanan is not far from Union City at all. The Ultraguard Gold (UPF) line of filters (made by champion) is by FAR the best oil filters for flow and filtration that have been made (Hard Driver) would be a close second. I have not seen a new SSR in person yet, if I were you I would buy the quantity of (UPF) filters that I would need for the LIFE OF THE car or truck (I have cases and cases of new Ultraguard Gold, Hard Driver, and Mobil-1 filters stored at my shop) just in case they stop production of them (UPF-44) in the future also!

VQ35DE, Where's the best place to purchase about 10 of the UPF-44 oil filters? My local parts stores and Chevy dealers don't seem to handle them.

GM says that 5.3 and 6.0s for 04 should use PF46s and that PF44s are not backward compatible. OK. I crawled under my 04 Suburban, built in Dec, 03 and it had a ..... PF-44. I think it's a no brainer, I'll use UPF44. Just ordered a dozen.
