Uni Filter NU-3258ST Multi-Stage Competition Air Filter

The Uni Filter NU-3258ST is a high-performance two-stage air filter designed for serious off-road and competition use. This multi-stage filtration system combines a coarse outer foam layer with a fine inner foam layer to maximize airflow while providing superior engine protection in even the most extreme dusty conditions.

Key Features:

• Two-stage foam construction traps more dirt than single-layer filters while maintaining excellent airflow

• Outer coarse foam pre-filters large debris while inner fine foam captures microscopic particles
• Completely washable and reusable—clean with Uni Filter cleaner and re-oil for continued use
• Unique two-piece design allows complete separation for thorough cleaning of both stages
• Premium open-cell polyurethane foam provides superior dirt-holding capacity
• Extends engine life by preventing harmful contaminants from entering the intake system

Uni Filter's competition-grade filtration technology has been trusted by professional racers and serious enthusiasts for decades. The NU-3258ST delivers maximum protection without sacrificing the airflow needed for peak performance.
