Advanced FCd Full Contour Design
DNA’s advanced FCd (Full Contour design) allows the filtering material to follow the contour of the air box precisely. This design makes use of the complete air box surface as an active filtering area.
Furthermore, the FCd design helps eliminate dead spots that can cause turbulence. This design approach supports increased airflow while maintaining the filter’s high filtration efficiency.
For the Triumph Speed Triple 1200 RS/RR, the FCd design provides a purpose-built fit within the existing factory air box.
98%-99% Filtering Efficiency
The DNA Air Filter uses 4 layers of DNA Cotton and provides a stated filtering efficiency of 98%-99%. This high filtration level helps the filter retain dirt while allowing increased airflow.
