Most Diesel engine warrentys will be voided using a K&N.
The paper will filter better but will get clogged faster even with twice the surface area so more airflow for a much shorter period of time. I don't want to spend hundreds on paper filters and there is no evidence that doing so will help. Maybe if you plan on this being the last truck you buy but I certainly don't fit in that catagory. I use K&N because I like their product but I don't go around claiming to be an expert on air flow and filtering properties nor do I claim that it's the best filter. K&N works for me and I have never had any trouble with it. Anything outside stock can void your warranty.
