PF63E vs PF63 ?

[milkmaster]

Alright!  Give me the skinny on this.  My 2021 GMC Sierra 1500 manual says PF63E for an oil filter.  I have looked online and see it some places while others cross it with just a PF63.  Some opinions say it is the same even, while others say the oil pressure bypass is a different pressure.  I am sure this has been beaten up before, but not as much as I would have expected.  Some places online I see the crossover to PF63 is a shorter filter.  Does the "E" stand for extended length or something?    First GM truck I have had in years.  What am I missing or need to know?

There is also a heavy duty AC Delco, UPF63R.

Oil pressure bypass is a different pressure is the key to the 63E.

The E was the revised version of the filter when it went to a 22psi relief valve.  GM has now gone back to just using a PF63. It is the same as the PF63E.  No change and why they dropped the E is beyond me but either one will work.

My understanding is that they made an updated PF63e that has the correct bypass psi from the E model, but now its just sold as PF63.  part number 12707246
