There was someone here recently who measured the Honda filter from Fram and the can gauge was thicker than the standard aftermarket Fram. So why does Honda spec a thicker can? Many thousands use Fram on Honda no problems, but maybe the new Pilot with its new oil pump put a lot off stress on a filter that maybe was on the marginal end of having a tight seam.
I think that was me, Im still not convinced of the measurements and the tread got so derailed I never did any further checking. It may indeed be thicker (an oft repeated fact) or it may not be.
I also never made an in-depth post about the obvious differences in the media.
Im just so sick of the silliness around here I checked out on both issues.
OP, I agree giving the Ultra a second chance would be prudent.
