FWF Air Filter Yamaha YZ 250/450F WR 250/450F 7970

The ProLine Filter has been developed over the last 18 months, with extensive testing in the United States, South Africa and Europe. Available now, this new filter offers the ultimate in riding in all extreme conditions, thanks to its profiled single-layer foam construction, which increases surface area and extends change intervals.

Like all FunnelWeb filters, the ProLine Filter features profile cut, single-layer, single-density foam that doubles the filter's external surface area without increasing the filter's original size. The ProLine Filter retains dirt – dust, sand and mud – over a larger area on its outer surface, ensuring optimal airflow is maintained to maximize engine performance and reliability.

The single-layer, single-density polyurethane foam has the added advantage of being easy to clean and the ability to maintain its original shape after countless washes. Overall, compared to conventional foam filters, the FunnelWeb offers more protection against dirt ingestion, has longer service intervals and maintains high airflow rates when dirty.

Funnelweb Proline Filter Highlights:

• Optimal airflow for longer riding time;
• Improved engine protection;
• Extended filter change intervals;
• Simple to install, clean and lubricate;
• Easy assembly.
