Its black construction provides a practical protective layer for applications exposed to wet riding conditions, while maintaining the airflow needed for efficient engine operation.

Uniform micron-sized openings allow air to pass through with minimal restriction while the silicone treatment helps repel water before it reaches the underlying filter or flame arrestor. This design offers added protection without replacing the need for proper filter maintenance or routine inspection.

The K&N RX-4990 Drycharger is reusable and built for dependable service in automotive and powersports environments. Its water-repellent treatment typically lasts one to two years, depending on use and exposure. Verify the wrap’s compatibility with your specific K&N air filter or personal watercraft flame arrestor before installation. This product is intended as a protective filter accessory and is not a replacement for the primary air filter element.
