What he said. There are only a few companies actually making filters anymore.
6637 is just the napa part number, thats it. (actually 66376)
Its a donaldson/tymar filter.
AFE is a completely different filter and its an oiled filter IIRC>
You are correct Sir...Open mouth & insert foot. Disregard my post...Picked up a 6637 NAPA today and was shocked when it was a reboxed Donaldson !!!

I bought the afe with the oilless filter, just hit it with the garden hose when its dirty and your good to go.like ccarrier said on the first page- no filter to keep replacing,more money initially but i believe cost effective in the long run.
