6637
 

ok was asking about covers whent to riffraff found this 6637 filter kit is it i think i like it how does it compare to afe

from the picture it looks huge will it give u more air flow than the afe stage II

I can't remember what the 6637 flows but depending on your mods and where you want to go, total CFM won't be the deciding factor. IMHO I would choose between the 6637 and the S&B since it filters better than the AFE and is less expensive.

Riffraff Diesel: S&B

I'm not sure how it compares, but it is a great filter.

thanx ill be ordering one soon clay i was looking at Platinum petes pictures hes building a cold air box for his looks like a great idea

I can't take credit for the airbox, I copied it from Chris (F350-6). Here is a link to the thread, post 72 has the links to the pdf files with the demensions/layout.
