The DNA air filter for the 2022 Honda CB 400 SF replaces the original filter and can be washed, oiled and reused. Its construction combines four layers of cotton between two layers of metal mesh, with a filtration efficiency of 98–99%. It is designed to increase the motorcycle’s airflow, horsepower and acceleration.
The pleated filter media has large-radius edges to make full use of its surface area. The frame is made of DNA PU, and the seals are made of EVA to ensure an airtight fit in the original airbox. FCd technology increases the filtration area by 20–80%. The filter is made in Greece and should be installed according to the motorcycle manufacturer’s instructions.
