The Outerwears ATV Pre-Filter, manufacturer part number 20-1066-03 and vendor part number 25-5803R, is designed to help protect compatible air filters on select Bombardier Outlander models. This pre-filter fits 2003–2005 Bombardier Outlander 330 HO 2x4 and 4x4 models, as well as 2004–2006 Bombardier Outlander MAX 400 HO IRS and Outlander MAX 400 HO XT IRS models. Verify the vehicle model and existing airbox or filter configuration before installation.
Constructed from silicone-impregnated micro-mesh, the Outerwears pre-filter provides water resistance while helping prevent sand, dirt, clay, and other unwanted contaminants from reaching the primary air filter. Its uniform micron-sized openings are designed to filter particles as small as 0.005 inch without noticeable airflow restriction. Dyno and flow bench testing has shown no significant loss of horsepower or air intake performance when this product is properly installed.
Dielectrically welded seams create a durable, sealed construction suited to demanding powersports use. The pre-filter helps extend service intervals for the primary filter and supports more consistent intake protection in dusty, wet, and off-road environments. The compact ATV-specific design is intended for a direct fit on the listed Bombardier applications, making it a practical replacement or protective upgrade for riders who regularly encounter abrasive debris and moisture.
