I bought a bunch of new old stock Fram PH6016 filters cheap on ebay for my motorcycle. Most of them are of the Allied Signal vintage. I wanted to cut one open before running them to make sure they were still ok. I was actually pleasantly surprised. The filter media was in good condition and not brittle, the anti-drain back valve was still very pliable and the plastic on the pressure relief valve was not brittle. The date code is A21431
