The DNA motorcycle air filter for the Triumph Bonneville Bobber 1200 replaces the factory filter and features a pleated element made of four layers of cotton gauze sandwiched between two layers of wire mesh. Airflow is 167.48 CFM, compared with 124.30 CFM for the factory filter—an increase of 34.74%—while filtration efficiency ranges from 98% to 99%.
The cotton material is oil-impregnated, and the element is supported by 5000-series marine-grade aluminum wire coated with epoxy resin to protect against oxidation. The frame is made of elastomeric polyurethane, while the EVA seals are factory-installed. FCd design technology allows the pleated element to follow the contours of the airbox and increases the filtration surface area.
