I noticed this too, I think it's kind of unique that Walmart now sells, AC Delco filters, Motorcraft filters, and Mopar too. I also think it's funny all of the anti-walmart slogans here, but it seems most people still shop there regardless.
I saw them the other day and picked one up for my Trailblazer. Now my Walmart carries ACDelco, Mopar, Motorcraft, Supertech, and FRAM. Air filters are still pure FRAM. I would like to see those FRAM cleanable filters.
