I have been watching all these cut open filter posts for a few months now and I have a question. Unless there is a horrible tear or missing louvers/holes/ADBV. How can we look at photos of a filter and say, yeah that's a great filter run that sucker 30,000 miles! Or man, that filter is [censored]! I wouldn't take that for free if someone gave it to me! Lately on BITOG if a cut open filter "looks nice" it's a great filter, run that sucker for ever. If it looks like something else, it's [censored]. So, is there any other way to judge a filter and is qualities or short comings other than internet photos? Is it possible to ascertain that a filter is good or bad just by looking at photos posted on the internet? Come on people, a Fram Ultra or NAPA Gold could look great in photos but still fail the basic purpose of a filter. With internet photos, can we tell if the filter media is plugged and used up or still good? I think not.
