The OUTERWEARS ATV Pre-Filter is designed for use with K&N HA-2501 air filters, providing an added layer of protection in demanding off-road environments. Its red silicone-impregnated micro-mesh construction helps shield the underlying air filter from sand, dirt, clay, and water while supporting consistent airflow. The pre-filter is engineered for riders who need dependable intake protection without compromising engine performance.
Dyno and flow bench testing has shown no significant loss of horsepower or air intake when using this product. The material contains uniform micron-sized openings that allow air to pass through while filtering particles as small as 0.005 inches in diameter. Its water-resistant design helps reduce the amount of moisture reaching the primary air filter during wet or dusty riding conditions.
Dielectrically welded seams provide durable construction and help prevent contaminants from entering through stitched areas. This OUTERWEARS pre-filter fits the K&N HA-2501 application and is compatible with select Yamaha and Honda ATV models, including the 2011 Yamaha YFM450FGP Grizzly 4WD EPS with IRS and Honda TRX250EX Sportrax models from 2001 through 2008. It also fits the 2002 Honda TRX250TE Recon ES with SRA. Manufacturer part number 20-1064-03 is supplied by OUTERWEARS for application-specific identification.
