The Outerwears ATV Pre-Filter Stock air filter cover helps protect your Honda ATV air filter from sand, dirt, clay, water, and other unwanted elements while supporting consistent airflow. Designed for use with the stock air filter configuration, this pre-filter uses silicone-impregnated micro-mesh material with uniform micron-sized openings. The result is effective filtration without a noticeable restriction in air intake performance.
Dyno and flow bench testing has shown no significant loss of horsepower or airflow when using the Outerwears pre-filter. The material filters particles as small as .005 inches in diameter and is water resistant, helping provide added protection during dusty, wet, or muddy riding conditions. Dielectrically welded seams provide a secure, durable construction for powersports use.
