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 154115, 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 154115 Air Filter to improve the absorption of dust debris.
