Uni Filter NU-1406ST Two-Stage Air Filter for KTM Dirt Bikes

The Uni Filter NU-1406ST is a premium two-stage replacement air filter engineered specifically for KTM dirt bikes. This high-performance filter is designed to fit perfectly in your factory air box, providing a direct replacement for the original equipment filter.

Key Features:

• Unique two-stage design with dual foam layers that separate for thorough cleaning and maximum airflow
• Ultra Seal grease groove molded into the sealing surface ensures a positive seal against dirt and debris
• Thin, durable base material is virtually tear-proof for long-lasting reliability
• Superior dirt-stopping capability without sacrificing airflow performance
• Each foam layer can be serviced independently for easier maintenance
• Trusted by factory racing teams including Yamaha, Kawasaki, and Suzuki off-road programs
• Made in the USA

Maintenance is simple—clean with standard grease-cutting dishwashing detergent, re-oil with foam filter oil, and reuse indefinitely. The two-stage construction allows you to service one layer while keeping the other installed, or separate both layers for complete cleaning. Uni Filter's proven foam technology delivers unsurpassed airflow and filtration performance for competition motorcycles and ATVs.
