Uni Filter NU-2311ST Multi-Stage Competition Air Filter for Kawasaki ATV

The Uni Filter NU-2311ST is a high-performance multi-stage competition air filter designed specifically for Kawasaki ATVs. Engineered with premium open-cell polyurethane foam, this filter delivers superior filtration and airflow for demanding off-road conditions.

How Uni Foam Filtration Works:

• Open-cell polyurethane foam is treated with specially formulated filter oil that creates a sticky barrier on the foam's web-like cell structure
• Dirt particles are trapped by the oiled foam strands, preventing contamination from reaching your engine
• Progressive depth loading utilizes the entire thickness of the filter as outer layers capture dirt, allowing downstream layers to continue trapping particles
• Prevents surface loading and maintains optimal airflow for up to 80% of the filter's service life
• Washable and reusable design - simply clean, re-oil, and reinstall for long-term cost savings

Key Benefits:

• Multi-stage filtration provides superior engine protection in dusty, harsh environments
• Competition-grade construction for high-performance applications
• Maintains consistent airflow even as filter loads with dirt
• Economical reusable design eliminates frequent replacement costs
• Direct OEM replacement fitment for Kawasaki ATV models

Ideal for racers, trail riders, and ATV enthusiasts who demand maximum engine protection and performance in challenging conditions.
