I emailed ACDelco about the possibility of using the PF63 in the place of PF48 on my 2013 Silverado. Here's what they said:
Dear Mr. xxxxx:
Thank you for visiting the ACDelco website.
In regards to your inquiry about PF63 oil filters, the PF63 is replacing the PF48 therefore any application that calls for a PF48 will now use a PF63. Again thanks for using ACDelco.
If you have any other questions, please contact our experts at the ACDelco support center by dialing 1-800-ACDELCO (223-3526).

ACDelco Internet Response Team
