I've used the K&N many times over the years without a problem. Last fill, I went with a Mobil 1 (M1-210A) because I read an article on Consumer Reports about their quality compared to all the others and it was dubbed best. I didn't notice any difference, so I tried an Amsoil (EA011) the most recent fill and didn't notice a difference there either. I'll probably just go with the Motorcraft FL-820S this summer when I change the oil. I just want a consistent quality built filter and I feel like Amsoil, Mobil 1, and Motorcraft will meet that need compared to others out there.
