I'm learned from the comments that Fram removed the wire backing from their Ultra model. My theory as to why they did it was to provide clearer product differentiation across their four models.
Below is from my Oil Filter Value Analysis table that is posted under that thread title. I sorted and set the filter (no pun intended
) for the Fram products.
I found the primary difference between the Ultra and the Titanium is the metal screen backing of the filter material. I believe Fram viewed customers struggling to rationalize the $4.00 incremental price of the Titanium if they could buy the Ultra with that same feature. The other item, and it's subtle, is the Ultra is called the Ultra Synthetic. This tells me Fram is targeting customers who prioritize synthetic media when shopping for a filter.
This is what I concluded from the data. As always, I welcome your thoughts and feedback.
