The Outerwears ATV Pre-Filter is designed for use with the Uni Filter RU-0840 air filter. This protective filter cover helps reduce the amount of sand, dirt, clay, and water reaching the primary air filter while supporting consistent airflow for off-road applications. Part Number 20-1090-01 is manufactured by Outerwears and is also identified by vendor part number 20-1090-01.
Built from silicone-impregnated micro-mesh, the cover provides water-resistant protection without creating a noticeable restriction in air intake. Uniform micron-sized openings allow air to pass through while filtering particles as small as 0.005 inches in diameter. Dyno and flow bench testing has shown no significant horsepower or airflow loss when using this product, making it a practical upgrade for ATV riders operating in dusty, sandy, or wet environments.
The seams are dielectrically welded for added durability and dependable protection during demanding riding conditions. The universal ATV pre-filter measures approximately 6.2 inches long by 4.8 inches wide by 1.0 inch high and weighs approximately 0.64 pounds. Confirm compatibility with the Uni Filter RU-0840 air filter and your vehicle’s airbox configuration before installation.
