Uni Filter NU-8513ST Multi-Stage Competition Air Filter for Polaris ATV

The Uni Filter NU-8513ST is a high-performance multi-stage competition air filter designed specifically for Polaris ATVs. This premium foam air filter delivers superior filtration and airflow compared to paper filters, making it ideal for demanding off-road conditions.

Advanced Foam Filtration Technology:

Uni Filter uses open-cell polyurethane foam construction that is pre-oiled with specially formulated filter oil. The oil is suspended on the web-like cell structure of the foam, creating a sticky barrier that traps dirt particles throughout the entire depth of the filter material. Unlike paper filters that load on the surface, this multi-stage design utilizes the full thickness of the foam, preventing air restriction for up to 80% of the filter's service life.

Key Features:

• Multi-stage foam construction for maximum dirt-holding capacity
• Pre-oiled and ready to install
• Washable and reusable for long-term cost savings
• Superior airflow compared to stock paper filters
• Designed for competition and extreme riding conditions
• Direct OEM replacement for Polaris ATV models

Maintenance:

When the filter becomes sufficiently loaded with dirt, it can be easily cleaned using Uni Filter cleaning solution, then re-oiled with Uni Filter oil and reinstalled. This reusable design provides excellent long-term value while maintaining peak engine performance and protection.
