K&N Air Filter Wrap Drycharger RX-4990 Black | Air Filter Cover

Protect your air filter with the K&N Drycharger RX-4990 Black. Silicone-treated polyester pre-filter Repels water & dirt while maintaining maximum air flow.

The K&N Air Filter Wrap Drycharger RX-4990 Black is a high-performance pre-filter sleeve engineered for round tapered air filters and personal watercraft flame arrestors. Constructed from durable, silicone-treated polyester micro-screen material, this wrap acts as an added defense barrier for your intake system.

It features uniform, micron-sized openings that allow high volume airflow while limiting the amount of moisture, mud, splashes, and large dirt particles from reaching the underlying filter. Stitched elastic openings ensure a snug, secure fit, making it easy to slip on or off during routine maintenance.

Best Uses

1. Off-Roading & Trail Riding: Protects intake filters from heavy dust, mud, and water splashes during off-road trail driving.
2. Wet & Rainy Conditions: Prevents water saturation on exposed air filters mounted in open engine bays or cold air intake locations.
3. Personal Watercraft (PWC): Shields flame arrestors from water intake in marine environments.
4. Extended Service Intervals: Extends the interval between deep filter cleanings by capturing bulk dirt and debris before it clogs the primary filter media.

Features

1. Silicone-Treated Polyester Material: Durable micro-screen fabric pretreated with a hydrophobic coating to shed water.
2. Uniform Micron-Sized Openings: Specifically designed structure that maintains airflow while stopping contaminants.
3. Stitched Elastic Openings: Elasticized top and bottom trim allow for quick installation and a tight fit around the filter base.
4. Round Tapered Fitment: Precision sized for round tapered air filters with a 6-inch base ID, 5-inch top ID, and 5.5-inch height.
5. Long-Lasting Water Repellency: Hydrophobic treatment stays effective typically for 1 to 2 years under normal conditions.

Benefits

1. Water & Splash Resistance: Prevents water splashes or mud spray from drenching your main filter media and causing engine choke.
2. Maintains Air Flow & Power: Micron-sized pores deliver low restriction so your engine keeps breathing for optimum performance.
3. Saves Maintenance Time: Keeps heavy dirt off the main filter, allowing you to clean the primary filter less frequently.
4. Protects Engine Investment: Blocks fine particulate matter, extending the service life of both the air filter and engine components.
5. Easy to Install & Clean: Slips on in seconds with elastic stretch trim and can be easily washed or rinsed off.
