That is interesting. The TSB is dated Feb 4, 2019 and our 2019 Acadia has a build date of April 10, 2019 yet came with the PF63e AC oil filter installed. Also interesting since the same reasoning of tighter tolerances and pressures were used when a TSB was issued stating to quit using the AC PF63 and only use the AC PF 63e.The 3.6 oil filter has been superceded to specify the UPF63R. There is a TSB on it for the LGX engine due to oil pressure and improved wall strength.
Thanks for posting this since there is nothing even in the 2019 Acadia Owners Manual it states an AC PF63e oil filter.
