The Outerwears 20-1023-01 pre-filter provides an essential layer of protection for your engine's air intake system. This black polyester cover fits over your existing air filter to block dirt, dust, sand, and debris before they can clog your primary filter element.

Key Features:

• 3-3/4 inch diameter x 4 inch length fits popular round air filters
• Hydrophobic polyester material repels water and moisture
• Maintains airflow and horsepower by keeping primary filter cleaner longer
• Washable and reusable for years of service
• Simple slip-on installation with elastic bottom band
• Black color resists UV fading

Outerwears pre-filters are manufactured using a special hydrophobic process that allows air to flow freely while preventing water penetration. This design is especially beneficial in wet, muddy, or dusty conditions where a standard filter would quickly become saturated or clogged. By filtering out larger particles before they reach your main air filter, the Outerwears pre-filter extends service intervals and protects your engine investment. When the pre-filter becomes dirty, simply remove it, wash with mild soap and water, allow it to air dry, and reinstall.
