Uni Filter NU-8506ST Multi-Stage Competition Air Filter for Polaris ATV

The Uni Filter NU-8506ST is a high-performance multi-stage competition air filter designed specifically for Polaris ATV applications. This premium foam air filter delivers superior filtration and airflow compared to traditional paper filters, making it ideal for aggressive riding conditions and competitive use.

Advanced Foam Filtration Technology:

Uni Filter's open-cell polyurethane foam design provides progressive filtration that utilizes the entire depth of the filter media. The specially formulated filter oil is suspended throughout the web-like cell structure, creating a sticky barrier that captures dirt particles on contact. As outer layers become loaded with contaminants, deeper layers continue trapping particles, preventing surface loading and maintaining consistent airflow throughout 80% of the filter's service life.

Key Features:

• Multi-stage competition-grade foam construction for maximum dirt-holding capacity
• Open-cell polyurethane foam optimized for high airflow and superior filtration efficiency
• Progressive depth filtration prevents premature air restriction
• Washable and reusable design for long-term cost savings
• Pre-oiled and ready to install for Polaris ATV models
• Outperforms disposable paper filters in dusty, dirty riding conditions

Easy Maintenance:

When the filter becomes sufficiently dirty, simply wash it with Uni Filter cleaning solution, allow it to dry, re-oil with Uni Filter oil, and reinstall. This washable, reusable design eliminates the need for costly replacement filters while maintaining peak engine protection.

Ideal for motocross, trail riding, desert racing, and other demanding ATV applications where maximum engine protection and performance are critical.
