PureOne is same/possibly slightly better than motorcraft and usually cost less. I have motorcraft on my contour and pureone on my escort right now. I haven't looked at the K&n for the contour lately, but when I looked at the one for the escort, it's smaller than pureone/purolator/motorcraft filter. I like having a bigger filter.
Don't waste money on a fram. Although some of their higher line ones may be OK, still not worth it. The PureOne is OE quality, has a 98% efficieny rating or whatever it is, and the silicone antidrainback valve or whatever it is.
