A DNA air filter can last as long as the motorcycle itself. The strict quality control applied to the manufacturing and to the choice of materials is one of the reasons we can offer a lifetime guarantee. DNA® High Performance Air Filters trap every dust particle, even the finest ones (below 5 microns), making sure only fresh, clean air reaches the engine. The unique, revolutionary FCD design is a DNA® innovation that uses over 80% more filtering area, significantly increasing airflow. The increased airflow of a DNA filter means more engine power and torque — specifically, gains of over +12 hp (a common result on some models), giving immediate throttle response and better control of the machine. DNA is constantly setting new targets, discovering and testing new materials and manufacturing methods so as to keep efficiency, power and protection at the highest level and always stay one step ahead: the benchmark, in other words, in high-performance air filters.
