The DNA motorcycle air filter replaces the original filter and is designed to increase horsepower and acceleration while providing 98–99% filtration efficiency. It is reusable, washable, and can be cleaned and oiled for reuse. Airflow is 3,668 lit/min, an increase of 66.7% compared with the OEM filter’s 2,200 lit/min.
The filter media consists of four layers of cotton between two layers of 5000-series aluminum mesh. The frame is made of DNA PU, or elastomeric polyurethane, while the gaskets are made of EVA. The FCd design follows the outline of the airbox and increases the filtration area by 20–80%. The filter’s shape fits the original airbox, and installation should follow the motorcycle manufacturer’s instructions.
