DNA, high flow air filter element. Sportster

DNA filtering media is made up of 4 layers of an oil impregnated ‘nafta’, surgical-quality cotton gauze, specially developed by DNA’s in-house R&D team. The cotton gauze is then sandwiched between 2 layers of Epoxy coated, Marine Grade aluminum wire mesh before being robotically pleated to DNA’s unique ‘large pleat edge radius’ patterns. The result is an extremely high-flow filter (98% efficiency) which exceeds any of today’s motorcycle needs. It offers increased potential performance, efficiency and drivability, combined with long-lasting durability.
