Description
A properly sealed air filtration system is critical to protecting your KTM 50 SX engine from abrasive dirt and sand while maintaining the peak airflow your carb demands. Twin Air’s pre-oiled dual-foam design traps fine particles without creating restrictive backpressure, giving you both longevity and responsive throttle feel. The eco-friendly bio-based oil won’t degrade under heat, so your filter stays effective through demanding riding conditions.
