having bought and installed 3 of those specific filters (7317 cross reference) all of them have been silicone gaskets premium guards. you much be a low volume area. need to either buy up the old stock to find a store with more commercial customers.Not having seen every application and their corresponding date codes, I couldn't accurately speak to that conclusion. And as seen by my CQ Prem. 84356 anecdotes posted, many can still be nitrile. That despite whatever description currently provided by AAP.
