Uni Filter NU-3241ST Multi-Stage Competition Air Filter for Yamaha ATV

The Uni Filter NU-3241ST is a high-performance multi-stage competition air filter designed specifically for Yamaha ATVs. Built with premium open-cell polyurethane foam, this washable and reusable filter delivers superior filtration and airflow for demanding off-road conditions.

Key Features:

• Multi-stage foam design captures dirt particles throughout the entire filter depth, not just the surface
• Open-cell polyurethane foam construction provides excellent dust-holding capacity
• Specially formulated filter oil creates a "sticky" barrier that traps dirt on foam cell strands
• Progressive filtration prevents surface loading and maintains airflow for up to 80% of filter life
• Washable and reusable design - simply clean, re-oil, and reinstall for long-term savings
• Competition-grade performance ideal for racing and aggressive riding

Uni Filter's unique foam technology works by suspending oil-wetted strands in the path of incoming air. As outer layers capture larger particles, downstream layers trap finer dirt, utilizing the full thickness of the foam. This prevents premature restriction and ensures consistent engine protection even in the dustiest conditions. When cleaning is needed, the filter easily washes clean and can be re-oiled for continued use.
