Yes I’m going to stick with the pf48. I called some local Chevrolet dealers and the service dept told me they list the pf63 for that truck but I spoke with ACDelco on the phone and they told me it’s not the same filter and now after reading the specs on the bypass it’s pretty cut and dry. Guess there’s a reason they are still listing the pf48 for this engine. Thanks

I don’t get why GM supposedly stated that the pf63 would replace pf48 in any application

Then is pf63 still ok to use?

Trying to figure out why in my owners manual they list the pf63 for the 5.3 and 6.2. But still calls for pf48 on 6.0... seems odd if only difference is length

Hi everyone just traded my 17 z71 1500 for a 16 2500HD 6.0. I have a case of pf63 filters but the truck calls for a pf48. I know it’s the same filter just shorter. Does anyone know if the pf63 is too long? Thanks
