K&N Engineering RU-2590DK Drycharger Air Filter Wrap, Round Tapered, Black

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 high 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. The K&N Drycharger is a silicone treated, polyester wrap that is made to cover K&N Air Filters or Personal Watercraft Flame Arrestors. They contain uniform micron sized openings that allow high air flow.

• Water Repellent Treatment Typically Lasts 1 to 2 Years

The K&N Engineering RU-2590DK Drycharger is a silicone-treated polyester air filter wrap designed to help protect compatible K&N air filters and personal watercraft flame arrestors from water and moisture. Its black, round tapered design provides a close-fitting protective layer while maintaining the airflow needed for efficient intake performance.

Uniform micron-sized openings allow air to pass through with minimal restriction, while the silicone treatment helps limit the amount of water reaching the underlying filter or flame arrestor. This makes the Drycharger a practical choice for vehicles and watercraft exposed to wet riding conditions, spray, or occasional moisture. The water-repellent treatment typically lasts 1 to 2 years, depending on use and environmental exposure.

Designed for automotive and powersports applications, the K&N Engineering RU-2590DK offers a reusable protective solution without replacing the primary air filter. Verify the filter or flame arrestor application before installation. The cover is not identified as emissions-certified for a specific application, and California Air Resources Board approval is not indicated.
