Universal, oval, washable and reusable high-performance sports air filter. Not approved for road use! The elaborate and elegant design with its uniquely coloured faux leather cover makes it particularly special for cafe racer and custom bike conversions. A larger filter area increases air passage and airflow, reducing fuel consumption and increasing engine performance. The DNA filter medium consists of four layers of special DNA cotton fabric held together by two coated aluminium wire mesh layers. The special pleating technique of the filter medium enlarges the inner radius of the pleat tips, and the resulting surfaces provide additional filtration. Cleaning and maintaining the filters is child's play thanks to the DNA service kit. Winner of the Red Dot Award 2017!
