Air filter question

I have been looking in to making my own intake and every one says to use the napa filter 6637 and a have also herd the wix filter 46673 and from what i understand they are the same thing. so i went on fleetfilter.com which i herd about from the org. but what i don't understand is with the wix filter 46673 the CFM is 425 and the stock filters CFM is 640 and that don't make sense to me why would you want to put the bigger filter on if the stock one will let more air through? just a thought

I used to use a Baldwin filter of the same size. I found that it got squeezed between the hood, inner fender, battery and fuse box. I went to a tapered Amsoil filter and get a lot more air moving now. You can hear it!

Just my $0.02.

I should've gotten into this before I got my S&B. My S&B intake sounds real cool, gives me a slight seat-of-the-pants performance, & gave me 2 extra MPGs, but now there's snow on the ground & I'm just worried about the oil bath.

To me the main reason to do the DIY is to protect the engine. The factory filter system leaked dust into mine and cost me an engine rebuild which was a lot of work and $$$.
It is just a nice benefit to get the increased air flow. As for the flow ratings of filters, I don’t know much about that but I do have some common sense that tells me more surface area = more flow at the same or tighter restriction. To me the only way to have more flow with less surface area is to sacrifice filtration.
