K&N Engineering RX-4730 Drycharger Air Filter Wrap, 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 RX-4730 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 intrusion. Its black wrap design provides an additional layer of defense in wet and demanding riding or driving conditions while supporting the airflow needed for efficient filter performance.

Uniform micron-sized openings allow air to pass through with minimal restriction, helping maintain strong intake airflow while limiting the amount of water that reaches the underlying air filter or flame arrestor. The flexible construction is designed for practical installation over compatible filter assemblies and is suitable for applications where added moisture protection is desired.

• Water-Repellent Treatment: Silicone treatment typically lasts 1 to 2 years, depending on use and environmental exposure.
• High Airflow Design: Uniform micron-sized openings support airflow while helping reduce water entry.
• Protective Filter Cover: Helps shield compatible K&N air filters or personal watercraft flame arrestors from moisture.
• Durable Polyester Construction: Flexible polyester material is designed for repeated use in demanding automotive and powersports environments.

The K&N Engineering RX-4730 is intended for use with compatible K&N filter and flame arrestor applications. Confirm filter compatibility and fitment before installation. This product is not identified as CARB approved, and California emissions regulations may restrict its use in certain applications.
