mmmmm about the filter getting wet...If you dry it out good will the filter still be alright???? Mine got pretty drenched offroad while crossing a creek

 

Kwik.....
You had mentioned in another post about the clamp and putting two together.. I just left West Marine and they have SS clamps up to 12 in and everything in between..

 

I was wanting to know how much difference there is between the NAPA 6637 and K&N which I should use K&N came with truck should I switch?

 

Yes, I purchased my "6637 or Kwik" filter from CarQuest and it is a Wix. It was a little tight going on but after that all seems good.

 

r_maddox - Switching from the K&N to the 6637 style intake is a question that is going to get answered 2 different ways, either "the K&N is the best" or "Dont use K&N" Its a matter of experience or preference. Myself, Kwik, and quite a few others have made the switch to the open style 6637 filter and have been very happy with the results. Personally I highly recomend it for better filtration and flow.

Here are some other part numbers for alternatives to use, I beleive they are all made my Duralite though.
