Is there a filter out there that requires no oil but fits my K&N system?
And is better that K&N?

 

Yes, and there's a forum designated to discuss intakes. It's called Exhaust and Intakes here -

The answer is yes. An Amsoil dry nano fiber element is the best one on the market. You might have to measure your opening to custom fit the K&N box, but it's allot easier just running your factory cold air box.

BTW -This info is only good for the 97-03 model years.

I'm not sure about the 04 + . You can check the Amsoil site to see what they offer.

 

Look in my photo album. There should be a pic of the Amsoil conical filter in my K&N intake. Only way to go!!
