The K&N Drycharger pre-filter wrap in blue is a silicone-treated polyester cover made to protect K&N air filters or personal watercraft flame arrestors. Its uniform micron openings allow high airflow while the water-repellent treatment limits moisture reaching the filter. The Drycharger typically provides water resistance for one to two years and helps extend filter service intervals in wet environments.
