I bought the stage 2 today, but accidently got the 5 gauge filter insted of the proguard 7....does this filter work better than the kn replacement that I had in the truck before? Do you recommend the prefilter?

I don't have the progaurd 7 on mine either, I did put the prefilter on just to help keep the big stuff and water off of the filter. So far it has worked perfectly. When installing I had to trim the box in order to make it fit though. I had to trim around the AC line and the shock tower with a dremel.

A pre filter is just a water resistant sleeve that fits over your filter to help keep water and large dust particles off of your filter. I use one to help keep water off the filter and also to help keep the filter clean so I don't have to clean it as often. click on this link and scroll down to the bottom there is a picture of the prefilters from AFE AFE stage 2
I always get mine from Outerwears.com which is who makes the prefilters for everybody else and they sell them direct for a lot cheaper. I believe AFE charges $41 for the prefilter whereas I got the same thing from Outerwears shipped for $28. Just call them and give them the AFE prefilter part# and they will quote you a price. The only difference is it will say Outerwears on it instead of AFE.

As far as the differences between Stage 1 and Stage 2, my understanding is they both flow the same, the only difference is the Stage 2 is enclosed in a box on 3 sides and the top which helps keep the turbo quieter. I went with the stage 2 to help with the turbo noise and also to help keep **** off the filter when I'm playing in the mud. I went out the other day playing in the mud and when I was done I had mud all over in the engine compartment but there wasn't anything on my filter just all over the box protecting it.

The PG7 is gold the non PG7 is blue.

the pro guard 7 is a more/multi layered filter supposed to give you better filtration. thanks for the reply guys i'm gonna get a pre filter.
