Universal, oval, washable and reusable high-performance sports air filter. Not road legal! The elaborate and elegant design with its uniquely colored synthetic leather cover makes it particularly special for Cafe Racer and Custombike 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 aluminum wire meshes. The special pleating technique of the filter medium increases the inner radius of the pleat tips, and the resulting surfaces provide additional filtration. Maintenance and cleaning of the filters are effortless thanks to the DNA service kit. Winner of the Red Dot Award 2017!
