The K&N Drycharger custom round tapered wrap is a silicone-treated polyester cover made to fit K&N filter shapes and personal watercraft flame arrestors. It restricts water ingress via uniform micron openings while maintaining high airflow, similar in purpose to K&N prechargers. Water-repellent treatment typically lasts one to two years, offering temporary additional moisture protection for exposed filters.
