The Outerwears Red Pre-Filter is designed to fit K&N PL1003 air filters and provide an additional layer of protection in demanding riding and outdoor environments. Manufacturer part number 20-1211-03, this pre-filter helps shield the primary air filter from sand, dirt, clay, and water while supporting consistent airflow to the engine.
Constructed from silicone-impregnated micro-mesh, the Outerwears pre-filter is water resistant and engineered with uniform micron-sized openings. The material filters particles as small as .005 inches without noticeable airflow restriction. Dyno and flow bench testing has shown no significant loss of horsepower or air intake when this product is properly installed over the compatible K&N PL1003 filter.
Dielectrically welded seams provide a durable, secure construction suited to repeated use. The red filter cover can help extend service intervals for the primary filter by reducing exposure to airborne contaminants before they reach the main filtration media. Verify that your existing filter is a K&N PL1003 model before installation to ensure proper fitment.
