I am lookin on genos right now at some fuel filters and such and I just came across the pre filters for the afe stage 2 kits.

With the progaurd 7 do yall think I should get the pre filter?
Will it cut down on the cfm any? If so is it noticable?

I had it explained to me that if I had the pg7 I wouldnt need the prefilter. But if I got the standard 4 ply filter I should get it and put the pre filter on. In either even I was told to take the prefilter off before racing.

What do you guys think?

 

I have used a pre-filter on all my AFE filters, Stage I standard, Stage I pro-guard 7 and Stage II Pro-Guard 7. The pre-filter will keep larger material(bugs, mud, etc.) from getting to the filter material and keep it cleaner longer and make it much easier to clean when needed. It also sheds water, not completely water proof but most water that is splashed on the pre-filter will just run off and never get to the filter material.

I don't know how much restriction it is, but not much and worth it to me.

 

I use one also and have sprayed mine with a spray water proofing.Let dry and reinstalled.

 

Where do you get the spray water proofing?

And thanks for the replies, I am gonna go ahead and add it to my order on genos.

 

Scotch guard, wherever you can find it.

 

Does the pre-filter need to be oiled like the filter does? If so, does this react with the Scotch-Guard?
Thanks.

No the pre-filter is not oiled. It is used dry.

 

I used what I spray my boots and wet weather jascket/gear with from the boot store.

 

Make sure you clean your pre-filter at least every 60 days or less. The only good way to clean them is to use dish soap and water....

 

I've been trying to get one from Geno's, and there back ordered, anyone know who has them in stock?? i need one by the 14th.

Try dieselmannor.com, I got mine from them.

 

At genos they only showed that the black ones are back ordered, so I got yellow, but maybe all the colors a back ordered.
