Just trying to drum up a discussion. Anyone here ever had a recent engine failure because of the filter? Since I have joined this site, I can think of 2 which considering the statistics isn't very many IMO. Anyone ever have a fear of running a non spec'd filter? Has anyone been able to identify a faulty filter and replace it before it created damage? I would hope I could identify a loss in oil pressure, CEL, faulty ADBV or other noise before any damage is caused. As far as warranties for the filters, I plan on running non spec'd filters once my stash diminishes so I doubt the manufacturer would do anything to help. Also as mentioned in another thread, keep your receipts! Even if I was running a spec'd filter, but had no proof of purchase, I would still be out of luck. No filter related issues for me as of now.
