Description
Dirt and debris are the silent killers of two-stroke performance. The Twin Air Pre-Oiled Air Filter for your KX250 or KX450 delivers dual-stage foam filtration that captures everything from coarse sand to fine dust without choking airflow—keeping your engine protected and responsive lap after lap. Pre-oiled and ready to install, it eliminates the guesswork and gets you on the track immediately.
Twin Air’s proven dual-foam design has earned trust across professional and amateur racing circuits. The coarse outer layer handles the heavy lifting against larger particles, while the fine inner foam catches micron-level contaminants while maintaining the airflow your engine demands. The seamless fusion between layers prevents dirt from accumulating in the gaps where filters fail.
