I just used my remaining stock of ACDelco UPF44 oil filters and see they are no longer available for purchase. Is there an equivalent filter to replace the UPF44 for the LS1 engine?

No. best thing is to send me the car and just try to forget.

you can still get upf44 filters here and there but you have to hunt for them. I know you can find them on ebay. hope this helps

UPF44 and Mobil 1 # M1-107 are identical in all respects. They are manufactured by Champion. Go 4 It !

Thanks much, my local stores carry them for $12.99. I will pick one up today.

I see the AC PF46E is listed as a replacement. Any problem with these filters?

Thanks for getting that info out about the Mobil ! filter. I like factory parts but can buy a Mobil ! filter much more easily, so I feel good, I put a Mobil 1 filter on with the last change.

Sorry about the above wise crack. I need a lot of attention.

Not at all. Been using them since I got my 04 back in 2010

I use the UPF44 Ultrguard Gold, I'm glad I bought three cases of them, they are getting harder to find.
