Funnelweb Filter - FWF527

Double the surface area, Twice as effective.

The FunnelWeb Filter was designed and is manufactured by Infiltration Pty Ltd, an Australian Company with more than 40 years of experience in off road motorcycle foam air filtration within the organisation. Utilising the latest technologies in open cell foam 3D profiling, the pyramid profile effectively doubles the filters outside surface area without increasing its overall size and, compared with conventional foam air filters, have been designed to;

• Trap and hold more dust on the outside surface of the filter
• Maintain optimal air flow by spreading dust build over an increased surface area.
• Enable longer filter service intervals.

Performance and reliability is crucial while adventure riding. When manufacturing the new KTM 690 / Husqvarna 701 / Gasgas ES 700 Filter cartridge, we aimed to address any possible shortcomings of the standard filter and craft a filter that could withstand the dust, debris and other harsh elements that come with long-distance adventure riding with minimal surface intervals. 

In addition to our Pyramid profile foam found across the entire FWF range, the filter boasts a host of Adventure-specific features: 

• The filter cartridge has ample rigidity, enabling it to be securely self-supported in the air box, while retaining regular flexibility for ease of cleaning and oiling.
• 10mm foam gasket ensures an air-tight seal over what can sometimes be anuneven air box surface, allowing no dirt or debris to enter the airbox.
• The lower, open pore foam layer firmly locates and seals the cartridge in the air box and effectively acts as a back-up filter.
• The upper pyramid profiled foam layer provides an increased surface area to trap andhold far more dust than conventional foam enabling a longer period between service intervals without restricting airflow.

This air filter is to replace the OE filter, if you have a Rade Garage Auxiliary Tank Kit installed please consider FWF469 or FWF513F.
