ACDelco PF663 - A listed PF48E Alternative

[MrkofXcellence]

When shopping Rock Auto today I noticed an ACDelco PF663 as a filter for my Silverado. This was confirmed on the ACDelco website. Finally, even amazon.com's fitment algorithm (which I don't trust) advised that it is a proper fit. I ordered a couple from amazon.com Does anybody know about this filter or have any experience with it? I'm tempted to try it on my Silverado, but I know nothing about it. I'm currently using a PF48E.

The PF63 is slightly longer. That's all. There was a TSB somewhere where GM allowed them to be interchanged.

Not PF63, PF663. Take a look on amazon. Different looking for sure.

Jobber filter? Says Professional....Not Duraguard, Satin Black paint.

I use Delco Ultraguard UPF48R.

My bad, I couldn't see the other six for some reason.

That's the PF61 you're thinking of.
