The DNA motorcycle air filter for the BMW R 1300 GS replaces the original filter and is reusable. It consists of four layers of cotton between two layers of metal mesh, with an elastomeric polyurethane frame and EVA gaskets. Airflow is 124.30 CFM, compared with 96.10 CFM for the original filter—an increase of 29.40%—while filtration efficiency is 98–99%.
The cotton filter media can be washed and oiled for reuse. The metal mesh is made of 5000-series aluminum with an epoxy coating, while the EVA gaskets are bonded to the frame with industrial adhesive. The FCd design makes use of the airbox’s contours and provides 20–80% more filtration area. Installation should follow the motorcycle manufacturer’s instructions.
