Always fun and interesting to watch when MMWA comes into a discussion, this just one example. Personally, I've often referenced it when topic of my standard practice of using aftermarket filters of my choice, even under warranty for my Hondas. That said, I understand the legal vs practical application of the "Act" and who has the deeper pockets. I'm willing to assume whatever risk (generally minor I think) there might be. Otoh, if others get some peace of mind using OEM, their vehicles, their call. I can give my point of view and long time experience on it, but ultimately it's a personal choice, not my job/place to convince otherwise. I expect same with my choices in 'some' aftermarket filters, which I'm confident don't pass muster with some. My .02
