The Uni Filter NU-1409ST is a high-performance air filter designed specifically for KTM dirt bikes. This premium replacement filter delivers superior engine protection and performance enhancement for off-road riding conditions.

Key Features:

• Revolutionary two-stage design that separates for thorough cleaning and maximum airflow

• Increases horsepower and torque output compared to stock paper filters
• Reusable and washable design for long-term cost savings

Uni Filter's proprietary foam technology traps particles on the surface rather than allowing them to embed deep into the filter material, making cleaning easier and extending filter life. The unique two-piece construction allows the filter to be completely disassembled for the most thorough cleaning possible. For best results, use Uni Filter cleaner and oil for maintenance. This filter is engineered to withstand the harsh demands of motocross, enduro, and off-road racing while providing reliable engine protection in dusty and muddy conditions.
