There is a thin foam filter under the dry filter that catch some of the fine dust before it gets to the stock paper filter.

The question is do I use the original foam filter with the new K&N filter or just throw out the foam?

 

this is on the 03 predator

 

Loose the foam.......just make sure you have oiled your K&N.......you might also want to mod your airbox soon too(cut holes in the back of it, like the one in my pics page)...........

 

The K&N instructions it says to discard the foam filter when using the K&N.

Thanks Chris

 

I would think the foam could wick away oil from the filter. You may want to look into a K&N pre-filter.

 

Can you get a Pre-filter, for the sqare K&N filter? The one use with the stock airbox im talking about.

 

Nope...........no prefilter for a drop in like that.........If you decide to drill the holes in the back of the airbox though, you can prefilter those........

 

dont destroy your airbox!!!! get a EHS RACING LID or a K&N LID! Why Drill holes in an air box when you can have something you can close up also???

 

hey hippy another case of opinion i dont think it will destroy there a alot that run that way i think daranello find out what would run best in your area from locals then do what you need

 

i dont think ill go with the holes, i like to ride in deep water and mud (the manual says do not go deeper than the footpegs) help me go deep!!
