more pleats = better filter
more filter media better than less
paper end caps are garbage
...on and on and on
Due to my line of work (independent research lab), I've had access to in-depth filter testing on almost all major brands -- Wix, Fram, STP, Purolator, Champ, M1, and many more. And I'm not talking about tests like those done on those hokey websites many on here reference (the ones with filters cut open and the components laid out). I'm talking the real industry tests (ISO 4548-12, burst, etc.). If you guys only knew how poorly some of your favorite brands performed you'd be shocked. Not to say there aren't people on here who have the facts much straighter than most, but even those guys are way off base many times.
For those of you on here truly looking for some insight into which filters perform best, please don't pay much credence to things posted on this board, as you will be left completely misinformed and your engine will hate you for it.
Funny how you have access to all this advanced research and none of it is published for anyone to read. We have to do our "hokey" research on filters because none of the major brands publish their data for peer-review or public consumption, they just rely on their "marketeers" to give us information. Let's see some of your data to back up your claims. I think you're just biased and you don't like what you read here because it goes against your preconceived notions.
Must be like when Castrol switched to Group III synthetic basestocks without disclosure, but their marketers kept telling us how superior Syntec was. No wonder we don't trust the major labels without independent verification.
