FWF, or FunnelWeb Filter, is an Australian air filter brand that specializes in the production of off-road air filters designed to help your motorcycle breathe better and longer, even in the most extreme conditions.•
 
The FWF Pro Line Air Filter features a single-layer open-cell polyurethane foam that enhances airflow to the carburetor, while its high-density design effectively blocks dust and dirt.
 
Its innovative multi-pyramid shape doubles the external air and dust collection surface without increasing the internal surface area, multiplying its filtration efficiency by ten. This allows your motorbike to breathe better, even in the most extreme conditions.
 
Washable and reusable, the FWF filter is built for durability, making it a top choice for off-road and adventure riders who need reliable, long-lasting engine protection.
 
Are you going on a long or remote trip? Not sure you have what you need to clean your filter? Just fit a pre-filter on and remove it instantly when dirty to start fresh again. You can either slip a new pre-filter or use your main air filter.
