Cut open a AC Delco pf64 filter that was on my 2019 Spark with around 7000+ miles on it. I thought the pleats looked looked really good so I took some pictures I should've gotten one of the anti drain back valve but it was in good shape and flexible. I've really started to like AC Delco filters as they're cheap, pretty well made even with the e-core and have a regular bypass valve
