I cut open a Fram Tough Guard yesterday. Yep, no surprises. Some sort of fiber board end caps on the filter. The filter media itself looked fine.
I'm tempted to take advantage of the Advance special on their house filters, just to cut one open. If I like what I see, then I'll use the other one. If I'm not particularly impressed, then I'll put the other one on my Dad's truck.
Another one that I may cut open would be the NAPA Pro Select. These are $2.69 for my Silverado and the Sierra.
