The K&N Drycharger® is a silicone treated, polyester wrap that is made to cover K&N Air Filters or Personal Watercraft Flame Arrestors. These Drychargers, which are similar to the K&N Prechargers, contain uniform micron sized openings that allow optimum air flow. Yet, due to the Drychargers silicone treated polyester wrap, the amount of water that reaches the air filter or flame arrestor is limited. K&N DryChargers are similar to PreChargers except they have been pre-treated to repel water.
Available in 4 different colors *Black, Blue, Red,Yellow *
What is a K&N PreCharger?
The K&N PreCharger is a specially designed filter wrap made to extend the service interval of your K&N Filtercharger when used in very dusty conditions. They are made from durable polyester material containing a uniform weave. The PreCharger will stop small dirt particles with minimal restriction to the airflow of the filter. The PreCharger is designed to be run dry and can be cleaned with K&N Filter Cleaner. The PreCharger is custom made to fit each application. Double stitched elastic openings assure that the PreCharger will stay in place. The PreChargers are available in a variety of colors, all with a silk-screened K&N PreCharger logo.
