So, Dennis -- are you saying that Fram filters do a better job than Mann or Mahle? Many list members believe otherwise, and some have advised that Fram filters are not at all suitable for a waterboxer engine. It is a lot easier to simply go down to a local auto supply and pick up a filter than it is to make sure to order up from an online vendor (for me, anyway). I believe one complaint against Fram filters was that they will "blow out," or the media will collapse under pressure. One list participant said that he found a Fram filter he removed had collapsed internally, and was simply not filtering.

I'm certainly not an expert on filters. Fram sells two different filters, one more expensive, and supposedly more effective, than the other. Is that one ok, the cheaper one not?

Thanks, David
