Because when I opened the box to look at the filter, it said CA3906WM on it, the WM at the end most likely meaning Walmart. So, are these cheaper or different than Fram air filters old elsewhere?
I opened a couple other different part numbers (both standard Fram air filters, including CA4309), and they did not have the WM at the end.
