The K&N Drycharger pre-filter wrap in red is a silicone-treated polyester cover sized to fit over K&N air filters or personal watercraft flame arrestors, with a 6in base ID, 5in top ID and 6.5in height. It allows high airflow through uniform micron openings while reducing the amount of water and contaminants reaching the filter. The water-repellent treatment typically lasts one to two years.
