Uni Filter NU-2372ST Multi-Stage Competition Air Filter for Kawasaki ATVs

The Uni Filter NU-2372ST is a high-performance multi-stage competition air filter designed specifically for Kawasaki ATVs. This advanced foam air filter utilizes open-cell polyurethane foam technology to provide superior filtration and maximum airflow for demanding off-road conditions.

How It Works:

The filter's open-cell polyurethane foam is treated with specially formulated filter oil that creates a sticky barrier suspended throughout the foam's web-like cell structure. As dirty air passes through, dirt particles are trapped by the oiled strands, making it impossible for contaminants to reach your engine. Unlike paper filters that load on the surface, this multi-stage design utilizes the entire thickness of the foam—as outer strands capture dirt, downstream strands continue trapping particles throughout 80% of the filter's service life without restricting airflow.

Key Features:

• Multi-stage foam filtration prevents surface loading and maintains consistent airflow
• Open-cell polyurethane foam construction for superior dirt-holding capacity
• Designed for competition use in harsh, dusty environments
• Washable and reusable—simply clean, re-oil, and reinstall
• Direct-fit replacement for Kawasaki ATV applications
• Prevents air restriction throughout extended service intervals

This reusable filter offers significant long-term value compared to disposable paper filters, while providing the enhanced protection and performance demanded by competition riders and serious off-road enthusiasts.
