The OUTERWEARS ATV Pre-Filter is designed for use with K&N SU-4002 air filters, helping provide an additional layer of protection against sand, dirt, clay, and water. Its silicone-impregnated micro-mesh construction is water resistant and engineered to help protect the primary air filter in demanding off-road environments. Manufacturer part number 20-1594-01 and vendor part number 25-5850 identify this application-specific pre-filter.
Uniform micron-sized openings allow air to enter while filtering particles as small as 0.005 inches 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 durable, secure construction intended for repeated use in recreational and utility ATV applications.
Fitment includes the 2011 and 2012 Suzuki LT-A400F KingQuad ASi with independent rear suspension, as well as 2004 through 2008 Arctic Cat 400 DVX models. It also fits 2003 through 2005 Kawasaki KFX 400 models. Confirm that your ATV uses the K&N SU-4002 air filter before installation. The OUTERWEARS pre-filter is designed as an accessory cover for the compatible air filter and should be installed securely according to the vehicle and filter manufacturer's recommendations.
