Ahh.. I think this is where there could be some slight confusion. The Fram made Honda filters with the cardboard insides were the larger ones. I remember that there was discussion on HT a while ago about Honda's switch to the smaller filters. These are the filters you're probably talking about. Now, I guess the question is whether or not there are construction differences between the different manufacturers' current (smaller) filters. I know you'll swear up and down that they make it to Honda's specs but I'd really like to see some people cut them open. Just for kicks.
