Uni Filter NU-3232ST Multi-Stage Competition Air Filter for Yamaha ATV

The Uni Filter NU-3232ST is a premium two-stage competition foam air filter designed specifically for Yamaha ATVs including Big Bear, Kodiak, Timberwolf, and Moto-4 models. This high-performance replacement filter is engineered to fit exactly like the original factory filter while delivering superior filtration and airflow for increased horsepower and torque.

Two-Stage Design Benefits:

• Dual-layer foam construction with independent servicing capability
• Outer layer can remain dry for maximum airflow in normal conditions
• Both layers can be oiled for superior protection in wet or extremely dusty environments
• Extended service intervals compared to paper filters
• Ultra-seal base is virtually tear-proof for long-lasting durability

Advanced Filtration Technology:

Constructed from open-cell polyurethane foam that works with specially formulated filter oil to trap dirt particles throughout the entire depth of the filter material. As the outer foam strands capture dirt, downstream strands continue trapping particles, utilizing the full thickness of the filter. This prevents surface loading and maintains optimal airflow for up to 80% of the filter's service life.

Reusable and Washable:

Unlike disposable paper filters, this Uni Filter can be easily cleaned, re-oiled, and reused multiple times, making it an economical and environmentally friendly choice for ATV enthusiasts and racers. The two-stage design allows for thorough cleaning of each foam layer separately for complete maintenance.

Made in the USA with over 40 years of proven performance in competition and recreational riding. Includes foam sealing gasket to replace deteriorated factory seals.
