The Twin Air Air Filter, manufacturer part number 154112 and vendor part number 715-4112, is designed to provide dependable engine protection and high airflow for select KTM motorcycles. Its dual-layer foam construction captures airborne dirt, grime, and sand while supporting consistent air passage for off-road riding conditions.
The thick, flat, greaseless sealing ring creates broad contact with the airbox and functions as a breathable gasket. The coarse open-pore outer foam traps larger contaminants, while the fine open-pore inner foam captures smaller particles without unnecessarily restricting airflow. The filter is slightly smaller than the original equipment filter to increase surrounding air space and improve circulation within the airbox.
Twin Air uses an adhesive formulated to withstand repeated cleaning, including cleaning with harsh solvents or gasoline. This reusable air filter is a practical replacement for riders who require reliable filtration, serviceability, and fitment for their KTM motorcycle.
Fitment includes 2004–2006 KTM 250 SX, 2005–2006 KTM 250 SX-F, 2006 KTM 250 XC, 2006 KTM 250 XC-W, 2006 KTM 250 XCF-W, and 2006–2007 KTM 300 XC-W models. Verify the model year and application before installation.
