I'm amazed at all the so-called "experts" on this board. If I had a nickel for every misconception stated on here, I'd be a billionaire. 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.
