Uni Filter NU-3240ST Multi-Stage Competition Air Filter for Yamaha ATV

The Uni Filter NU-3240ST is a premium multi-stage competition air filter engineered for Yamaha ATVs. This high-performance replacement filter utilizes Uni Filter's advanced two-stage foam design to deliver superior filtration and maximum airflow for demanding riding conditions.

Two-Stage Filtration Technology:

The coarse outer layer stops the larger particles and the fine pore inner layer gives the ultimate engine protection. This dual-layer construction allows the filter to trap more dirt while maintaining optimal airflow, extending service intervals and keeping your engine running cleaner longer. The two-stage design separates for thorough cleaning and maintenance.

Key Features:

• Made from open-cell polyurethane foam for superior dirt-stopping capability
• Ultra Seal grease groove on sealing surface ensures a perfect seal in the stock airbox
• Fits exactly like the OEM filter with no modifications required
• Washable and reusable—simply clean with grease-cutting dish soap, re-oil, and reinstall
• Pre-oiled and ready to install right out of the package
• Made in USA
