We have been checking production dates, the guys who have been buying cases production dates range from 2015 to may of 2018, so it looks like old stock is all that is available. The 2018's are nice because they are cheese grated design so great flow, I was happy to get those. But the older stock will still be great imo. We haven't had anything made after may 2018 for the hemi filter. My trans filter has a date of 2017. If anyone sees a production date later then may 2018 for rp filters please inform syn thread.
opps looks like maybe the 10-48 cases were sold as well. Man they had a bunch left, someone must have bought a bunch.
