High-Flow DNA Air Filter Design

The DNA Air Filter features DNA’s advanced FCd design. This design supports the filter’s high-flow performance while maintaining effective filtration.

Moreover, the filter provides 40.94% more airflow than the KTM stock foam filter. The DNA filter delivers 129.60 CFM, while the KTM stock foam filter delivers 91.95 CFM.

Therefore, this filter offers a significant increase in airflow for the KTM Duke 125, Duke 250, and Duke 390 series.

98-99% Filtering Efficiency

The filter provides 98-99% filtering efficiency under the ISO 5011 standard. It uses four layers of DNA Cotton to provide this level of filtration.

Furthermore, the filter combines its high-flow design with effective filtration. This makes it suitable for the specified race-use applications.

Race-Use Application

DNA designed this filter as a High Flow Air Filter for Race use. It suits the KTM Duke series listed below.

For the 125cc and 250cc bikes, fuel recalibration is necessary for proper function. For the 390cc bikes, fuel recalibration is recommended for optimal performance.
