Hey rebornhondaneer, I just read your post about the k&N filter. The K&N actually increases airflow over the paper filter. It stops just as much debris as a paper filter from getting in your engine. The increased airflow is what makes the extra power. They are not that hard to clean either. Nor do they have to be cleaned that often. So to me a K&N is worth $100. But that is just my opinion.
