K&N 6.625in Base ID / 5.25in Top ID / 9.5in H Round Tapered Black Drycharger Air Filter Wrap

K&N Black Drycharger Air Filter Wrap - Round Tapered (6.625" Base | 9.5" H)

Protect your high-flow intake with the K&N Round Tapered Black Drycharger Air Filter Wrap. Features water-resistant silicone-treated polyester to stop splash and dirt.

The K&N Drycharger® Air Filter Wrap (MPN: RC-4780DK) is an essential protective sleeve engineered specifically for round tapered performance filters. Constructed from a durable, silicone-treated polyester fabric, this pre-filter wrap features micro-thin, uniform openings designed to allow max airflow while arresting water droplets, road splash, and large contaminants before they hit the main filter element.

Whether you operate an off-road 4x4, track vehicle, or personal watercraft, exposure to rain, wet conditions, mud, and dust can prematurely clog your oiled filter. The Drycharger acts as an initial line of defense, repelling moisture and trapping larger dirt particles without causing restriction in throttle response. Tailored with precise dimensions (6.625-inch base ID, 5.25-inch top ID, and a 9.5-inch height), it slips over compatible cone filters with a snug, elastic-style fit.

Best Uses

1. Off-Road & Trail Vehicles: Ideal for trucks, Jeeps, and UTVs driving through muddy paths, sand dunes, or dusty conditions.
2. Wet Weather Driving: Adds water-repellent protection for open-element intake systems exposed to high spray or rain.
3. Personal Watercraft (PWC): Protects flame arrestors and air intakes on jet skis from marine splash and salt spray.
4. Track & Motorsport Use: Extends interval cleaning periods for high-rpm engines during intense driving days.

Features

1. Hydrophobic Coating: Treated with premium silicone solution to actively deflect water splash and moisture.
2. Precision Micro-Mesh: Built with uniform, micron-sized polyester openings that preserve essential high airflow levels.
3. Custom Tapered Fit: Dimensioned specifically for round tapered filters (6.625" Base ID / 5.25" Top ID / 9.5" Height).
4. Durable Construction: Made from resilient polyester designed to resist UV rays, heat, and physical abrasion.
5. Washable & Reusable: Can be easily removed and cleaned with water or mild soap for repeated long-term use.

Benefits

1. Protects Engine from Water Ingestion: Drastically reduces the volume of liquid reaching the primary filter during heavy rain or water splash.
2. Extends Filter Service Intervals: Traps bugs, dirt, and dust first, meaning you won't need to clean and re-oil your primary air filter as often.
3. Maintains Optimal Airflow & Horsepower: Prevents early mud and debris buildup, keeping air intake velocity high for consistent performance.
4. Easy Slip-On Installation: Installs in seconds over your existing air filter without tools or disassembly required.
5. Cost-Effective Engine Insurance: Protects your performance air filter investment and engine components at a fraction of the cost.
