The OUTERWEARS ATV Pre-Filter Stock, manufacturer part number 20-2506-01 and vendor part number 25-5901, is designed to help protect the factory air filter and intake system on select Polaris RZR models. This pre-filter fits the 2009–2011 Polaris RZR 800, RZR 800 S, and RZR 4 800 models, including the 2010 RZR 4 800 and 2011 RZR 4 800 EPS.
Built from silicone-impregnated micro-mesh, the OUTERWEARS pre-filter provides water resistance while helping block sand, dirt, clay, and other unwanted debris before it reaches the air filter. The uniform micron-sized openings filter particles as small as .005 inches in diameter without noticeable airflow restriction. Dyno and flow bench testing has shown no significant loss of horsepower or air intake when using this product.
Dielectrically welded seams provide a secure, durable construction for demanding off-road environments. The pre-filter is intended for stock intake applications and offers an added layer of protection for riders operating in dusty, muddy, or wet conditions. Verify the vehicle model and intake configuration before installation to ensure proper fitment.
