AC Delco Oil Filter PF63... Questions on Filter Revisions....

SoCal Angler · 2024-10-09T22:58:12Z

I read this over on the GMC Terrain forum today. Not sure if any of this correct, but I thought I'd share on this forum for some input. There are three different part numbers so that tells me there are three mods/generations of the same part.

I purchased a few of the PF63 filters over at Wal-Mart earlier this year....I'll need to check the part numbers. My truck had its oil changed at GM dealer in July...I'll climb under my truck and check for part number there as well.

"I'm sure many are aware that the early ACdelco PF63 [89017525] was upgraded to the PF63E
Then the PF63E, was superseded, back to the PF63 [12731742] in 2021? with a higher check valve of 22psi.

In 2024, it was again upgraded to the [12735811], keeping the bypass psi @22, but increasing the diameter of the intake ports dramatically, which allows a higher volume of oil flow to be filtered.
My local A-Z, had both in stock, and could see the difference first hand.

Being a lifelong GM fanatic, I always used AC-Delco, especially when under warranty and never had one fail or lost an engine."

I just purchased a 2024 Silverado 2500HD w/ the 6.6 L gasser motor. The owner's manual lists the ACDelco PF63 or a GM12707246 filter. Is this another new version?

Duramax Diesel Engine Oil Filter Update for 2023

September 20, 2022

The PF63 engine oil filter (Fig. 5) is the new recommended filter specification for 2020-2023 Silverado 2500HD/3500HD, Sierra 2500HD/3500HD, Express, Savana; and 2019-2023 Silverado 4500/5500/6500 models equipped with the 6.6L Duramax diesel engine (RPO L5P, L5D).

Fig. 5

The PF63 engine oil filter will be the factory-installed filter for applicable 2023 models equipped with the 6.6L Duramax diesel engine (RPO L5P). The current PF26 engine oil filter also is compatible with these diesel engines. (Fig. 6)

Fig. 6

The PF63 filter is 3/4 inches (19 mm) narrower than the PF26 filter, but it has a taller pleat height, which maximizes volume efficiency and cold flow performance. (Fig. 7)

Service Information and the Parts Catalog will be updated shortly. For more information and part numbers, refer to #PIP5870.

Yes, the e-Core filters were just redesigned. Baseplate tin was eliminated, some improved construction internally.

Nothing wrong with using the PF63E or the now "dropped the E" versions, both are acceptable. Heck, even if you found old stock of the pre E filters from when the PF63 came out you can use those.

Just construction changes is all. Still the PF63, same specs just updated design which means new 8 digit part #.
