The DNA Filters P-K9N18-01 motorcycle air filter is designed for the Kawasaki Z900 and uses multiple layers of oil-impregnated cotton gauze. Its filtration efficiency is stated as 98–99%, while airflow reaches 190.30 CFM—an increase of 45.15% compared with the factory filter.
The filter media consists of four layers of cotton between two layers of wire mesh. The frame is made of polyurethane elastomer, and the seals are made of EVA. DNA FCd design technology shapes the pleated filter to match the contours of the airbox, making use of its surface area.
