The Twin Air Replacement Air Filter for Powerflow Kit is designed to provide dependable engine protection and efficient airflow for select KTM motorcycles. Manufacturer part number 154210, also identified by vendor part number 715-4210, this replacement filter is engineered to fit KTM 85 SX (17/14) models from 2005 through 2012, as well as 2008 and 2009 KTM 85 XC models. It is a direct replacement for the Powerflow kit air filter and helps maintain consistent intake performance in demanding riding conditions.
The filter uses a dual-layer, open-pore foam design to capture airborne dirt, grime, and sand before they reach the engine. A coarse outer foam layer collects larger contaminants, while the fine inner foam layer traps smaller particles without unnecessarily restricting airflow. The thick, flat foam sealing ring provides broad contact with the airbox and functions as a breathable gasket, helping support a secure seal and improved air passage.
Twin Air formulates the adhesive to withstand repeated cleaning, including exposure to harsh solvents or gasoline when proper filter-service procedures are followed. The filter is slightly smaller than the stock filter to create additional air space around the element and promote improved circulation within the airbox. This design supports reliable filtration and airflow for off-road motorcycles that operate in dusty or sandy environments.
Fitment: 2005-2012 KTM 85 SX (17/14); 2008-2009 KTM 85 XC.
