Napa 6637 filter Question

Does anyone know if the Napa 6637 air filter will fit inside the K&N FIPK Gen II box? I want to get rid of the K&N air filter but want to keep the existing K&N box. Or should I just start over with the intake? Any help would be great. Thanks.

I can measure the filter tomorrow and you can get an idea how big it is. Just guessing I bet it doesn't fit. The Napa 66 is a BIG filter.

I know on my 2002 F-250 the filter fit on the tubing. I removed the metal shroud that was provided by K&N. I have had no problems with my set up since I switched to the 6637 filter. I could have left the metal shroud inplace. But I removed it with future plans to make my own out of diamondplate aluminum.

Do you guys have the DIY intake or the K&N set up? I saw the Napa 6637 is a big filter but wasn't for sure if it would fit. Measurements would be great. Also, I was wondering if I should just build a new intake? Thanks for your help!

I had the K&N cold air intake set up. But after I seen how crappy the K&N Filter is. I replaced the filter with the napa filter. If fit with no problem on my 2002.

I found this online for the WIX filter that's supposed to be equal......

Height: 12.380
Outer Diameter: 8.500

I use a Baldwin PA2818 and can measure it tomorrow. There's a bear in my driveway right now and I don't feel like wrestling tonight.

Fit? It is just shoved in between the fuse box and the battery. It's cool. Went driving in the mountains today. I turned off the radio so I could her it work! I love it. Jury is still out on any mpg improvements.
