I'll revisit one last time on this one-when you buy the eBay 6 pack, be absolutely sure to inspect all 6 filters for dents, loose internals, any other obvious issues. The eBay vendors take these returns, that have been subjected to multiple shipping trips, & shove them into a USPS Flat Rate box with little or no padding (because it won't fit!), and they ROUTINELY get damaged in shipping. There is nothing inherently wrong with an Ultra, IF it is not beat up, the cans are just not that strong. I wish Fram would take the Bosch Distance Plus can, baseplate, and a coil spring & put an Ultra element & ADBV in there-that would be the best non-bypass oil filter one could buy. As I said before, I've never had any issues getting credit or replacement filters for damaged Ultras off eBay.
