TwinAir Air Filter 154117 for KTM 85SX 2018 to 2020. Also fits on the 85 to 2018 Husqvarna TC2020.
Over 40 years ago, with the sandy and grainy soils of the Netherlands causing engine failures which resulted in the simple foam and / or paper filters causing a lot of trouble to the motocross rider as they lacked protection .
The revolutionary design of the TwinAir Air Filter 154117, fused into a double-layer (now widely copied) combines performance and protection.
The fused layers of open-pore foam and fine internal foam trap even the smallest particles. The new, more rounded design stimulates air flow. Reduced seams are made possible by a revolutionary micro-gluing process.
Shorter seams = more foam = more flow.
It is important to spray a lubricating oil on the TwinAir Air Filter 154117 to improve the absorption of dust debris.
