Absolutely. It is out of the ordinary for it to be marketed the way it is. I'm not sure about how the NAPA USA website is laid out, but Canada's is very, very basic. You enter your application and it'll list all the filters with line code, part number, part, and comment.
As for the warranty issues, yes I'd say good luck in court, too. That's why I do have some skepticism about what the warranty actually is. My reference to the Bosch Premium's warranty on a couple sites wasn't to disparage the Bosch Premium (which I use regularly), but to show that sometimes websites display whatever the heck they want.
For reference, here's the warranty information from Napa Canada about the Ultra-8 Brand 3611307, which is said to fit my G37. "Free of Defects in Material & Workmanship during the Period of Sevice Life Recommended by the Engine or Equipment Manufacturer. See Complete Manufacturer's Warranty."
Now, at least that sounds more plausible. Of course, there's no link to the "Complete Manufacturer's Warranty," but there may be something on the box at NAPA. And no, I'm not that curious to find out. I can get Bosch for under $5, why gamble with something unknown that will undoubtedly cost more than that.
