Uni Filter NU-2333ST Air Filter for Kawasaki ATV & Dirt Bike

The Uni Filter NU-2333ST is a high-performance foam air filter designed specifically for Kawasaki ATVs and dirt bikes. This reusable filter provides superior filtration and airflow compared to traditional paper filters, making it ideal for off-road riding conditions.

How Foam Filtration Technology Works:

• Open-cell polyurethane foam is treated with specially formulated filter oil to create a sticky barrier that traps dirt particles
• The oil is suspended throughout the web-like cell structure, making it impossible for dirt to pass through the foam strands
• As outer layers capture dirt, downstream strands continue trapping particles, utilizing the entire thickness of the filter
• Prevents surface loading and maintains consistent airflow for 80% of the filter's service life
• Washable and reusable design—simply clean, re-oil, and reinstall for extended filter life

Key Benefits:

• Superior dirt-stopping capability in dusty, off-road environments
• Maintains consistent airflow even as dirt accumulates
• Economical and environmentally friendly—reuse instead of replace
• Easy maintenance with Uni Filter cleaning and oiling products

This direct-fit replacement filter is precision-cut to match OEM specifications for proper sealing and performance on compatible Kawasaki models.
