Haven't seen these filters for sale in eons, they seem to have gone the way of the dodo. While shopping at Rockauto I stumbled across a closeout on these for $1.12 each. The shipping costs at Rockauto can sometimes get out of hand, but if you buy enough of these, you can get them for a very low price.
All the closeout deals tend to come from the same warehouse, so you can combine these with wiper blades, light bulbs, other stuff that's on sale for pennies on the dollar, and then the shipping isn't such a nuisance.
I ordered eight though I wanted to order a lot more. I find that when I stock up on oil filters, I end up trading in or selling the vehicle before I ever get to use them all. I have at least three or four filter types (several to a dozen of each) that I can't use.. But at least once, I've bought a vehicle that used the same oil filter as a previous one.. So I tell myself they will serve a purpose-- someday!
The size in question is a UPF2, aka PH8A (in Fram terminology). Most larger Ford engines from the 80's and 90's use this filter. If you have the room (i.e. if the filter fits), you can run a PH8A equivalent filter in place of a PH16. Luckily my old Ford pickup and my Land Rover Discovery can both run the PH8A-- maybe I will get through all these after all!
I have no idea if this filter is available in other sizes, but for the price you can't go wrong. Can't say I've ever run this filter before, but it seems to be of a premium variety... Anyone know the specifics of this filter, Ultraguard Gold? Synthetic media? Clearly there's a silicone gasket and threaded end bypass, but can't discern much else by looking at it.
Appears the ADBV may be nitrile rubber, but as the filter is mounted near-vertically on both my vehicles, this is a non-issue for me.
