BMC air filter for the Husqvarna Svartpilen, Vitpilen 250 and KTM Duke, Adventure and RC Series, 2020 to 2023. It swaps the factory filter for a washable, reusable high-flow element in place of paper, raising airflow and horsepower while trapping dust, dirt and harmful particles to protect the engine and prolong its life. Riders get better throttle response, acceleration and engine efficiency, and many report improved fuel efficiency. Fitting is straightforward with basic mechanical skills and standard tools. The filter is cleaned and re-oiled for long-lasting use, saving money over time. It is a rectangular panel filter with red pleated media in a red frame, a dark grey foam seal and orange tabs at top and bottom.
