The Stage 2 Air Filter is designed to improve airflow, torque, and overall engine performance for KTM motorcycles. It features advanced DNA® FCd (Full Contour Design) technology and is designed to work exclusively with the DNA® Stage 1 Air Filter.

When combined with the Stage 1 filter, this system provides up to +95.99% increased airflow compared to the stock KTM/Husqvarna air filter, while maintaining an excellent 98–99% filtration efficiency for reliable engine protection.

The upgraded setup delivers 73.30 CFM airflow vs 37.40 CFM with the stock paper filter, significantly improving engine breathing and throttle response.

Installation instructions are included. Fuel injection recalibration is recommended but not required. Designed for road, off-road, and race use.
