The Outerwears ATV Pre-Filter is designed to provide an additional layer of protection for compatible Uni air filters while maintaining dependable airflow for off-road performance. Its silicone-impregnated micro-mesh material is water resistant and helps shield the underlying filter from sand, dirt, clay, and moisture. The precision-engineered material uses uniform micron-sized openings to support consistent filtration without creating a noticeable restriction in air intake.
Dyno and flow bench testing has shown no significant horsepower or airflow loss when this pre-filter is used. The material can filter particles as small as .005 inches in diameter, helping reduce the amount of abrasive debris that reaches the primary air filter. Dielectrically welded seams provide a secure construction designed to withstand the demands of ATV riding and repeated exposure to dust and wet conditions.
This Outerwears pre-filter fits Uni air filter applications on select Honda and Yamaha ATVs, including the 2006–2008 Honda TRX450ER with electric start, the 2006–2008 Honda TRX450R, and the 2004–2007 Yamaha YFZ450. Verify the vehicle model and air filter application before installation. Manufacturer part number 20-2007-03 and vendor part number 25-5852R are included for accurate product identification.
